That's another great point, decision making, I've always liked games where depending on what you do, you can change the whole story, Red Dead Redemption 2 had something like that, but without going into so much depth, other games I've tried in that style where it is combined with relationships are some visual novels.

But it's difficult to introduce decisions and cover all the other points favorably, since by having many variables, the development of the game could be extended a lot, but it would be fantastic...
