My Ideas:
-stimpack-heal civilians to gain karma. (like after witnessing a fight)
-poison-use on civilians gain negative karma.
-some type of personal vehicle(motorcycle, car or truck from death race sort of thing)
-better and more companions such as mini death claw after reaching a certain level or certain perks activated.
-less tribes/factions(1-3 max).
-fallout shelter but in fallout 4 on the pipboy or in your homebase, something like that as mini game with achievements.
-better DLC
-bigger map, richer and more liveliness throughout the wasteland, not every where would be wiped out by a nuclear war. it would just be contaminated with radiation. bigger cities, more secrets and easter eggs.
-climate change.
-better night/day cycle.
-communuity mods on console(xbox one).
-co-op, 2-what ever for online, especially with base building. if not at release, sometime in the future for fallout 4.
-less hacks and cheats
-better hardcoe mode(less traders, caps, weapons. Food and water and stimpacks are kept under 50-100 in the entire map/game play.
-terraforming?
-better and more stats, perks, skills, etc....
- remote controlled weapons(example, rc car with explosives for that kamikaze racer, fully automated .500 caliber sniper rifle(somewhere around that )
-law/authority.

Game is confirmed as single player only, and also confirmed there are no drivable vehicles.

Other than those two, most of your ideas aren't bad. Except the factions one? Why less factions?

Also, what do you mean less cheats and hacks? There weren't any really, just glitches and exploits, some of which were patched out.

edit: Also confirmed, mods are coming to the consoles. However, since Script extenders are unlikely to be allowed on the consoles along with anything that could place strain on the hardware (higher rez texture packs for example), You won't have access to all the same mods as the PC.

Oh, nevermind. But uh, a lot of your suggestions are simply "better this" which doesn't really go into detail as to what exactly you want. Obviously we all want the game to be better.

No co-op fallout ever is my hope. Co-op is a cheap and kind of annoying gimmick being used in triple A gaming and I think we shouldn't make everything two player.

Pro-tip: Cut down on your usage of the word 'better' and try to explain what you think would make a specific aspect of the game 'better'. It's a subjective term, not everybody will agree with you.

EDIT: "Mini deathclaw" and "rc car with explosives for that kamikaze racer" made me cringe.

You need better suggestions

Um ... most of those things are already there. Few others confirmed not there. What are you wanting exactly?

Incredibly vague, and some of your ideas would mean making major changes that would never be implemented in a 5 month period.

You want 1-3 factions max, but a bigger map? Kind of counter intuitive, if you ask me.

Well now you're just being antisocial, not wanting to play with friends in Fallout.

Just kidding, I agree 100%.

-stimpack heals or gradual returning health like skyrim would help keep NPCs from dying

-poison may be there

-vehicles already confirmed not to be in the game, besides vertibird rides

-who knows what the companions will be

-who wants LESS factions? thats ridiculous

-minigames exist on the pipboy, doubt shelter will

-'better' isn't a great suggestion

-pretty clear from news it's bigger

-a weather system is confirmed if that's what you meant

-nocturnal enemies would be cool

-mods to some extent already confirmed for the Xbox One

-no. just no. god and jesus no. and a confirmed no

-don't use hacks when you learn of them if you dont want to

-Nv's hardcoe was pretty much all it needed to be, challenging but not survival-horror level

-not sure what terraforming would add. the planet is livable. [censored] up, but livable

-depends

-sure, why not. could be cool

-jails would be a nice change from the 'kill all offenders'

Agreed 100%.

-healing NPCs would be nice
-so would a new way to deal with them
-no vehicles
-better companions yea but i dont think a mini deathclaw qualifies as "better"
-less factions is about as bad an idea as unleashing Cthulhu
-why fit a game we already have in the game?
-goo DLC should be a given
-bigger, more alive maps would be best
-climate change? like having different types of environment in the game? agreed
-how do you improve going form day to night?
-naturally there will be mods
-remember how i said less factions is as bad a cthulu? multiplayer makes cthulu looks cuddly and loveable
-less hacks? cheats? neither of those things exist afaik, do you mean glitches?
-good hardcoe mode would be nice
-no major terraforming, this is not minecraft
-SPECIAL and the current skills are pretty good as far as i can tell, maybe share osme ideas about what can be added?
-we have C4 in FO4, thats technically remote controlled
-there is law, there has always been law and authority in FO, usually in the form of whoever has the biggest gun in town
