From my forum that got closed:

Here's some of my ideas on along which lines I would like some aspects of Fallout 4 to be made (I posted this (IIRC) before Fallout: New Vegas was even annouced, and once again last year, but made some changes so I'm not just reposting the same thing over and over again). Whether or not all the following would actually work in the game, is beyond me as I'm not a game designer, but at least to me it sounds decent on paper.
The WALL OF TEXT:

A minimenu:

There would be a minimenusystem that would trigger various functions needed during the gameplay. Pressing (for example) the mousewheel would open up a list (somewhat similiar to Fallout 1 and Fallout 2) beside the cursor that would present commands like Enter Worldmap, Heal, Heal Other, Repair, Rest/Wait etc. If well implemented, this could potentially offer a greater gameplay diversity through bigger possibilities for direct skilluses in several situations.


General gameplay:

The general gameplay would be quite similiar to F3 and F:NV. You roam around the wastes doing quests and exploring. But combat would be less frequent unless the player decides otherwise - in other words, you could pick some of your random fights. (Though I'd very, very much prefer it, I'm not suggesting ISO/TB gameplay, since I don't believe for a second that Beth would implement it no matter what. <_< )

This could partly be handled through wildlife AI, which would be set less aggressive in general. An aggression stat would be implemented which would vary from species to species - from completely neutral (only defensive combat) to total aggression (hostility almost immediately). The animals would have their own immediate surroundings, or personal spaces, somewhat like in Risen and Gothic series, and partly in F:NV. Get too close and you get a warning sign from the critter giving you time to get out of their space, linger and be chased off (or be attacked, if you don't flee). The radius of the space and the time you are tolerated in it would depend on the critter.

The mainquest would be scaled to a certain degree through chaptering it (not visibly, as in presenting a loadscreen: Chapter 1: In which you slither out from the uaginal cavity and learn the first lessons of life, but through certain major events through the main quest). And after those, the game would replaces some of the lower level enemies with higher level ones in the MQ areas - defeating which (if not gettin past by other means) would require you to level up some more. Or through a nonlinear levelscalingsystem where, for example, when one starts the game at level one, the enemies in the levelscaled zones would range from 1 to 10, and after one hits somewhere between levels 12 to 15 (which ever works the best) some of the lower level creatures scale up to about level 18 to 25 (but not all, to not make the world appearing to spin around the player too much). This would offer both, challenge and sense of progression to the player, as one becomes better than the current enemies before they scale up again.

There wouldn't be any quest- or enemycompasses, but there would be (toggleable, perhaps) minimap in which you could see the living beings in immediate vicinity. Perception would determine the range in which you see things, and with a perk (with appropriate requirements - outdoorsman and perception, for example) you could tell the difference between friendly (green dot), neutral (yellow dot) and hostile (red dot) targets.

The questcompass would be replaced by mere markers on the map which would point towards a general area instead of the exact target. And with that, the quest descriptions would be more accurate.

The wrist pipboy would be scrapped and replaced by a more handheld PDI like contraption, which would offer a more userfriendly inventorysystem (something like mix of what Morrowind or S.T.A.L.K.E.R. had, for example) with less scrolling while still holding the tabs to sort items by their nature, a one page charactersheet much akin to the original games. Opening inventory wouldn't pause the game (could be tied to difficulty - normal and beyond: No inventorypause, for example).

Skillcap would remain at 100, but the cost to raise them would rise as follows: 1-50 1:1, 51-75 2:1, 76-100 3:1, the point being, the better you get the more difficult it is to get even better - this would make a maxed skill equal to skillcap of 175 - and I think it'd be easier to utilize the full scale of the skill, if it caps at 100 (instead of having skills cap at 200 or 300). Also, the gaps between levels would be raised:

How it is now (first number is the level, the second XP needed to reach the level from previous point, the third is total amount of XP needed to reach that level):


How it should be (first number is the level, the second XP needed to reach the level from previous point, the third is total amount of XP needed to reach that level) for example:

The formula I made may not be correct, but the point remains.


Map and Travelling:

A return to the classic worldmap system (with some tweaks to make it look more... erm, "modern"). The actual FPP/TPP playground area would be roughly about 2x the size of Fallout New Vegas; and the area is divided into 5-7 (or so) hubs scattered in the worldmap which vary in size and content. General gameplay in those would be about the same as in F3 and F:NV, run around and do local quests and explore.

When you enter the node you could spawn at any "formidable" (as in settlementlike in size) location you've already found. The first time entering a node you would spawn at the side of the map on special spawnpoint for that purpose (which could be used later on too, of course).

Outdoorsmanskill is reintroduced (or merged within the Survival skill) and works similiarly to Fallout 1&2 with the difference that nonhostile encounters are always avoidable should the player so decide (to decrease the amount of loadscreens).

There would be pacing options for fast trave:
Cautious - Traveling takes substantially more time (25% or so), but the player gets a bonus to the chances of avoiding encounters (+20 or so to outdoorsman).
Normal - Normal traveling pace, no pace related bonuses or hits, encounters rolled straight with outdoorsman skill.
Rush - Traveling takes substantially less time (25% or so), but the chances of avoiding encounters would be lowered (-20 or so to outdoorsman).
(and of course, stuff that utilizes time to make the system worth anything)

The worldmap itself is zoned in couple of ways:
- The farther away from the starting position, the harder the enemies and vice versa; but there is still a (small) chance to encounter harder enemies on starting grounds and vice versa, based on outdoorsmanskill, luck and placement of the zone (but still keeping the MQ areas within reasonable range of enemies).
- The map is zoned into territories, which each have their set of unique enemies as well as a few commonones that can be found on every zone.

Each zone has about 5-7 small maps for random/special encounters, which are either hostile or nonhostile, and are based on the topography of the location in the worldmap and the contents of the encouters would be based on the zone in which it occurs.

The visitable locations on map would be as follows: A settlement - with explorable wasteland around it to provide smaller sidequest and exploring. Or just a visitable location like a majorsized building, militarybase, factory etc. They could even include two settlements, but in general all towns would be much bigger than those in Fallout 3 or New Vegas.

Each settlement has its own set of architecture (not too different from other settlements, but so that one can tell the difference), general theme and mindsets. These are small things, but they would add a lot of variety to the game.

Entering worldmap from a node would happen through the edges of the map. In Fallout 3, when you bumb to an edge of the map, you get a popup message that says: "you cannot go further that way" - now it would be like this: "e) enter worldmap".

To not have to always run to the edge of a map, you could use the minimenu command "Enter Worldmap", which could not be used indoors, during combat or if there are enemies nearby. However, escaping combat through the edge of the map would be possible.


Repairing:

Repairing happens either with repairkits, by gunsmiths in towns/caravans, or by a duplicate.

The kits would repair a fixed and relatively large amount of CND and have limited amount of succesful uses (and would offer a small bonus to the skill and crit. failure) each, but they would be expensive to buy, weight a somewhat hefty amount and would also be weakened and eventually broken by a certain amount of critical failures and general wear. Gunsmiths and repairmen would be very expensive but would get the job done no matter what. A duplicate would repair a small amount of CND (with no bonuses or hits to skill or crit. chance) so that you'd have to weigh the benefit of losing the weapons monetary value against the increase in CND (at least at early stages of the game).

Success in repairing is dependant on repairskill (a diceroll happens, dreadful I know). And the repairing takes a certain amount of time (few seconds) depending on the chance of success.

One would now be able to repair guns and armor beyond his/her skill but the further above the skill they go the harder they would get to repair. The math is irrelevant (as long as it complements the premise), but here's a quick idea on how it could go:

After the guns/armors condition is above the skill, the amount going above is turned into percentages that is taken away from the skill. IE: skill = 30 and rifles condition = 80. Condition - skill = 50. 50% of skill (30) is 15. So trying to repair a weapon in condition of 80 with a repairskill of 30 would give a chance of success of 15%. This is not necesserely realistic, but it is assuming that the more shiny the condition gets, the more difficult (but not impossible) it would be to repair it further.

Guns and armor would also have a chance for a critical failure if an attempt to repair fails. Critical failure, instead of repairing the gun, has a reverse effect. The chance would be from 1% to 10% (depending on the weapon) if a trait or a perk doesn't raise/lower it.

The increased hardship of repairing would be compensated via much slower degredation rate (based on the weapon, of course), though the effects of CND (jamming during firing, reloading disorders, rate of fire, damage, buying/selling values) would also be much bigger and frequent.

There would also be a possibility to repair broken robots or computers or what ever there is to repair, by pointing the target opening minimenu and selecting repair.


Healing & drugs:

Stimpak usage would be animated, so no more smashing a quick key for dozens of stims in few seconds (I like this method more than the concept of heal overtime from HC-mode of F:NV). The speed of the animation would be dependant of the related skill (doctor). More over stims now would always heal the same amount (no skill effect in there), and they would come in two variations: stimpaks and superstimpaks. Both of which would be rare and expensive (so that you cannot live off of them, but also have to rely on other methods of healing) and superstims much more so than ordinary stims.

The player would have a tolerance meter which would measure how much the player can medicate himself before overdosing. Overdosing would cause an instant loss of health according to how much the limit is surpassed and would also cause some visual distortions and statloss. The effect would last for a while and the time would be depending on endurance and doctor skill (and perks/traits that would modify it). The tolerance meter slowly lowers itself after the medication is done, and the magnitude it is filled is dependant on the drug used (powerful drugs - like Jet and superstims for example - obviously fill it more quickly), related skill and perks/traits modifying it. Using food as a healer would not affect the tolerance meter, but food would have a heal-over-time effect.

Doctorskill would be reintroduced and so would manual healing. Manual healing would be similiar to Fallout 1 & 2 (only a few uses/24hours - they would take few in-game hours to be completed - success is determined by skill), and couldn't be used in combat or when enemies are nearby. Healing cripples wouldn't be possible with stims or sleeping, but would require manual healing and the ability to heal cripples would be dependant of the doctorskill and the skillrequirements of the crippled bodypart (head and torso would be harder to treat than legs and hands), otherwise a doctor is a must see.

Manual healing would be entered by the minimenu, which would also have the "heal other" option to heal a companion or other alive being in need of assistance.

Healing through sleeping would work similiarly to Fallout 1 & 2.

Addiction would need a doctor or a certain amount (pretty long) of time to heal. Radiation poisoning needs a doctor or radaway (which would be rare and expensive).


Gunplay & VATS (should it be implemented):

Skills would now have much heavier effect on waivering than what it is in F3, utilizing the skill and STR requirement system from New Vegas (but more heavyhandedly). In addition, the players stance, movement, weapons type and recoil also would affect it.

The normal (according to skill) situation would be standing still and aiming through iron sights (which would reduce waivering). Crouching would give a small bonus to accuracy and going prone would give a slightly bigger bonus (with the bonus from aiming coming on top of that). The tradeoff with going prone and being accurate would be extremely slow moving and turning, and it would take its time for the player to get up and ready the weapon again. Firing from the hip would cause bigger spread. Movement would also give a hit to accuracy -- the faster you move, the bigger the waivering with ironsights and spread with hipfiring. Recoil would work dynamically based on the gun used, and would throw the aim off a bit with each shot (while bursting, the amount of recoil per shot would stack up eventually leading to firing straight up -- with hipfire, the "offaim" would be a bit smaller, but the spread would increase).

Guns would do generally more damage and the damagestats would be ranges. IE: Huntingrifle - dmg 11-20, like in Fallout 1&2, but with growth of related skill raising the minimum amount closer to the maximum (though not as far as up to having a static damage, there would always be some range left).

In vats you would now have an option to choose a firing mode. Rapid fire - a hastily aimed rapid shooting towards the target; or aimed shots, which would be the opposite of rapid fire.

Rapid fire would lower the accuracy a bit and you could only target a foe as a whole; but it would spend less actionpoints, while aimed shots would cost more and calculate the accuracy without minuses, and you would be able to target specific body parts. The bonuses and hits of chosen stance would be similiar to those in realtime firing.

Being prone in vats would force you to choose a firing sector (so that the player doesn't spin like a dreidel in all directions while being the most accurate he can). Prone position would also be the most expensive stance to fire from, while standing would be the cheapest, and being crouched in the middle. The player would be able to change his preferred stance in VATS, but at a cost.

Lockpicking:

Success is determined by skill so that you can try to pick any lock from very easy to very hard; and NO minigame involved. It would work somewhat like repairing; lock level - skill (if the skill is under the lock level) = percentual number that is taken from the skill. If the skill surpasses lock level, the chances are purely skillbased with maximum chance of success being 95% (this, the max chance, would go for every chance based system). And the percentual chance would be presented when moving the reticle over the locked object: E) Pick lock [Very hard: 13%], for example.

Lockpicking would be animated so that you either see your characters hands doing the job (FP view) or seeing your character from behind (TP view). You would have the ability to turn your head (or the camera) some ways left and right to see if someone is coming - so the game doesn't pause during the picking. But looking away from what you're doing, would have an effect (see below).

Picking locks would take a certain amount of time depending on your skill and level of the lock (aka the chance of success). When attempting, there would be a timebar similiar to what Vampire - The Masquerade: Bloodlines had. Skill would give bonuses to the time it takes to pick a lock in such manner that you don't get bonuses to picking hard locks before your skill surpasses maximum level of normal locks. More over, the bonuses would stop stacking up after your skill surpasses the next level of difficulty (no bonuses to picking normal locks after skill level of 75, for example, depicting that there is no way to open that kind of lock any better - other than with a fluke).

Each lock would have a certain amount of tries before (if you keep failing) the lock jams for a certain amount of time (preferably at least a couple of weeks, so that your attempts at just waiting at the lock for it to unjam would be a tedious job and prevent exploitation of the system). Moreover locks would have a chance for a critical failure that would immediately jam the lock despite if it was you first attempt, and critical success, which could occur at any point during the time it takes to pick the lock -- both of these chances would be very small.

This system would also be fit for hacking.


Difficulty settings:

The difficulty setting would affect the following: Staring points of skills (this would work so that easy players would be able to max out almost everything and the harder you go the less you can max and the more you need to rely on specialization) and the gaps between the levels, the availability and prices of supplies (money, weapons, ammo, armor, meds, food etc), the number of enemies encoutered, starting health, slight changes on damage and enemy health modifiers, the severity of negative effects (crippled limbs etc).


TL;DR?
Make the game lean less towards the TES style of gameplay - find a better middleground in between - to create a greater diversity between the two franchises.

The END
