I find it quite strange that you would be OK with it if they just call it an action adventure.
Also I do not think that open world has to be sandbox.
Honestly the gang wars are, to me, as expentable as a bullet after effects, ability to play baseball and such. Those are sandbox elements could be cool, yes. But I'm OK with open world being background and the story the focus.
That said, Yes, I do miss some crime system, cops AI, drivers AI...
In F4 I could help settlements, grow vegetables, help settlements, build settlements, helps settlement and much more... but I couldn't care less about the characters and factions. Ultimately I do not want to interact them any way.
That is why I prefer CP, even though I can't help settlements here.
I completely agree with not really caring about characters in FO4, except Dogmeat
But I think the reason for that is how well the characters are acted in CP, because they really nail that part. Which in contrast is probably in my opinion the weakest point in both FO4 and Skyrim, the acting here is just way off to the point that you really don't care much about them.
In regards to the rest, to me all these things is what helps make it immersive, it might be waste of time being able to go to a bar and drink or have a good time with Jackie or Judy etc. Because eventually it might not give you any XP or items anyway. But purely from the perspective of immersion, which clearly is what CP is aiming for, these things matters. Almost as much as how your character look despite it being 1st person, whenever you open your character sheet and your "Badass" merc look like something that just came from a circus arena, that ruins immersion as well.
And honestly in these types of games, I think such things are expected now, due to GTA. So if you copy them, you should expect players to also expect these things to be there and maybe even improved on.
Even Mafia (I think it was) you could work as a taxi driver, I think it was. Can't remember if you could do something else as well.
In regards to it being fine for them to just call it an adventure game, is not true, I want them to make it into a RPG as they said they would.
And for them to do that and make it one that I would really enjoy for the long run, I prefer that they copied from what is possible in Fallout and improved on that, rather than GTA. And if they don't care to add extra functionalities, then at least open it for modders and let them mod the hell out of it.
