I don't think it was done out of necessity, we had games like siphon filter that had this action aproach, and that we could aim
I don't think the classic camera means it's an old game
Until Dawn uses it and nobody criticizes it....
While i respect that you prefer the original way the game played I disagree pretty much 100% that it should have stayed like that.
Also Until Dawn is a choose your own adventure game, where the camera style aids in the horror cinematic feel it is going for. It, and this RE2, are not remotely same in any way besides being horror games.
