When you play violent games, you're just wasting your time shooting fake creatures and there's no sense of accomplishment really when you're done. If you play a game like KR:AI (http://ps2.ign.com/articles/753/753015p1.html ), you're actually improving a real-world skill (the game actually detects how well your intonation and stuff is, and scores you accordingly) that's good to have. How about that?
