Disclaimer:
This isn't suggestions or speculation based and isn't a place to suggest ideas but rather to discuss what your vision of a good or bad Fallout game is.
Let's keep this thread civil and show that we can't debate in a rational, constructive manner with the utmost respect for one and other.
As the topic title suggests, what could make Fallout 4 a fantastic game or a disappointment?
Make:
Thought provoking, complex, original and coherent writing.I'm not waiting with baited breath but this would really impress me.
In a new location for the series.
Primarily new factions and not resting on pre-established ones.
A continued trajectory of rebuilding and society starting to move past the devastation of the great war.
Ditching the rule of cool and making everything and anything believable and coherent first cool second, so that means not fixing some giant and supremely complex robot with wonderglue and any riff raff lying around the citadel.Or the BOS/Enclave/Harold or F.E.V magically appearing in D.C
Improving upon C&C by adding in consequences for dialogue choices like pillars of eternity or a complex karma system.
Break:
Multiplayer of any sort (don't see it happening thankfully)
Rule of cool being ubiquitous.
Skyrim's leveling system
The bos or Enclave playing a large part in the narrative again.
The game returning the D.C or the storyline of D.C (unless it was masterfully done, MASTERFULLY!).
No level cap like skyrim and watering down of special or skills in general.
Turning the world into a mindless sandbox with player created bases and vehicles with the purpose of mindless frolicking and armageddon.
Races or any kind and especially any cures for ghoulism.
Voice character.
This is off the top of my head I'll edit in some suggestions and tweak my list a little in due time.
