So, as a Fallout fan, i was thinking about some endgame content that can make gameplay almost infinite. In endgame of Fallout 4 you one shot everything and cleared areas recaptures very slowly with same and weak enemyes, which makes the game a bit boring. I wrote a few ideas that might keep the interest of playing in endgame. Some of the people(including me) loves building settlements, and some of them so much(including me) that they want to build up every possible settlement in the game to the mini-city status. What can make this fun and not the boring routine? => :

? Rebalanced attacks on the settlements.

There are many comments people saying that they didnt see a single attack in 100 hours of gameplay and some seen only few. Suggestion: Attacks procs only 1(optionally maybe more) time once a day and covers all settlements. Means if you have one settlement only this settlement may proc attack, if you have 20 settlements only one(optionally more) of them may be attacked in one day period to prevent spam. Optional, proc starts 7 days after capturing the settlement.

So, Defence Zero = 100% attack on settlement once per day (it's greedy and brutal world, you know)

Defence 0.1x of food and water sum = 90% chance of attack on settlement.

Defence 0.2x = 80%

Defence 0.3x = 70%

Defence 0.4x = 60%

Defence 0.5x = 50%

Defence 0.6x = 40%

Defence 0.7x = 30%

Defence 0.8x = 20%

Defence 0.9x = 10%

Defence 1x = 5%

Defence 1-2x = 5%-2.5%

Defence 2-3x = 2.5%-1%

(Optional) Defence 3x+ = 1%- chance

Full settlement occupation by enemies and monsters. You have only few hours to respond to a radio request for help from settlers, otherwise the settlements will be attacked even without your presence and possibly captured or destroyed (depends on attackers level and you defence level and quality). All mortals settlers will be killed during capture, all immortal(companions, quest NPC, etc.) will flee to the nearest settlement.

? Settlements level and status.

The bigger and successful the settlement is, the bigger the level and status of this settlement. Status and level determines by population, high tech structures, level of shops, amount and quality of furniture and decorations, maybe even equipment of settlers, etc.

Status - Settlement lvl 1-5,

Status - Township lvl 1-5,

Status - Trade City lvl 1-5,

Status - Pearl of the Commonwealth lvl 1 only (hardest to reach).

Titles can be whatever you want. Add a new dependency in settlements - Prosperity(can be mixed up with settlement level), which relies on :

a.Food (amount of different food types that settlement produces),

b.Water (the better the water station is, the better the level is),

c.Furniture and Decorations (same fundamental),

d.Power level and quality.

It will be good to add power level and prosperity level to raiding attacks on settlements formula, so attackers level and amount of enemies depends on settlement status.

? Rebalanced "Cleared Areas" and other locations in game recapture rate.

Cleared areas can sometimes(lets say 1% chance per day, but separately from each other) be captured by different type of mobs. Mob type - random, mob level depends on your level. Captured areas are shown in red on the Pip-Boy map with the unknown status when your starting Eyebot spy sees one. Eyebot spyes - seeks for captured locations, can be crafted in settlements with rare resourses (see p.5). Different levels of Eyebots.

Level 1 "name" - can inspect around 5 locations per day for capture status,

Level 2 "name" - can inspect around 7 locations per day for capture status and determine type of mobs,

Level 3 "name" - can inspect around 10 locations per day for capture status and determine type of mobs, mob level, quantity and equipment.

First eyebot you must craft using rare resourses(see p.5) which you will find by yourself in "new" recaptured areas.

? Rebalanced difficulty, Monster level, new legendary Behemoths, new legendary Mirelurk Queen, new legendary Bosses.

Few words about difficulty. Some people(including me) like challenges, like to make some tactical moves to kill over-leveled and over-geared enemies. And i also like to spam the sh*t out of my weapons. For that it will be good to add Options in difficulty levels. Personally i use mod "Create Your Own Difficulty Rebalance" but its not enough even on max difficulty settings (i use player damage multiplier 0.1 (0.5 default Survival multiplier) and enemy damage multiplier 6.0 (2.0 default Survival multiplier). Im pretty happy with enemy damage but even with 0.1 my damage multiplier (5x lower than on Survival) im still one-shoting most enemies with my super sledge, even without perks like Ninja (4x,5x,10x sneak melle attack damage) and Better Criticals. One shoting with 5x lower! damage than on survival and without most powerfull damage perks in game, think about it... So making Customizable Difficulty will make most of the players happy. And add some new legendary Bosses and Big monster, which can be in charge of raiding attacks. Imagine settlement attack of Legendary Behemoth and 10-20 master super-mutants, Legendary Mirelurk Queen and 10-20 different types of mirelurks, etc. Imagine synthetic mirelurk egg generator, which can be crafted using rare Mirelurk Queen loot(see p.5) plus some synth technology and which produces some amount of eggs per day, and so on...

? Rare resourses.

Needed for endgame structures, eyebot spyes, etc. Obtaining in new recaptured areas from area bosses(leaders) which make recleaning a necessary part of endgame.

P.S.: The main purpose of this thread is to inspire some developers and mod makers. I would definitely pay for my favorite game DLC with almost infinite balanced gameplay.
