I wish they made as much effort to design clever and believable AI behaviour in games.
And I like pretty graphics as much as the next gamer, but I'm not comfortable anymore with having to buy even more expensive hardware that heats up the room and sounds like a jet engine. Maybe that's why I enjoy indies these days.
It's awesome, regardless. I'm impressed how far we've gone with real-time rendering, and both the maths and the hardware feats behind it. I remember optimizing a rendering loop in assembly language, and being proud of the crude result with no lighting, no filtering, as we had in games back then.
