I didn't read the whole thing yet, I will come back at it later on but for now i have to say one thing." I, however, think it is a problem with the game. The game simply doesn't acknowledge the fact you have companions with you, and ignores them completely, like they are not there." ->That's a real problem.
It's infuriating that Larian chose cute 3d cinematics over showing more of your companions characters. Their cinematics are really nice and cool to watch but why all I get as a reaction is " gale approves, astarions dissaproves". Like can't they say something? Intervene? Minsc, Viconia, Anomen, Korgan -> All those guys would run in the middle of a conversation being like " I don't like this, we should do it in a different way. "
That's what made them human, that's what made us love or hate them(hate in a good way..). I already talked about it somewhere but I can't emphasize this enough. Companions need to step up their game.
The only two moments I actually remember are Astarion interventions against the beast hunter in the swamp and gale message after his death. Everything that happens in the camp is nice too but why do they ignore everything that happens around them? It feels...awkward.
