At the moment, I just have Madden and NCAA. I'm thinking of getting something else, possibly two games. I want to get Resistance 2, but with Killzone 2 around the corner, I think I'll just wait to see how that is before I get Resistance 2.
Little Big Planet is another option. Not a big fan of Call of Duty. Uncharted and MSG4 were the last games I played before football season.
Any other recommendations? For PC also. Just playing TF2, was wondering if there's anything else out right now worth while.
