any major or minor change that you think should - and realistically could - improve in games in the near future. i'll name a few, for FPS games... (1) clothes separate from character bodies (this is improving) (2) hair. no more bald space marines. (3) gravity and friction. in FPS games, there is no convincing connection between a player's feet and the ground. (4) realistic reaction to walls. if a character runs into a wall, or walks along a wall (especially if they're dragging alongside it), their posture should change. their hand position should change (if i run at a wall full speed, i'm going to put my hands up before i hit it) little things like that tip me into the uncanny valley now you go.
