To avoid mess threads like this, next time just say something like "I've got XX.XX in credit and am interested in games A, B, and C. Which one do you guys recommend?" Otherwise it's way too broad of a question and this lovely community comes out to talk shit. I kinda like how everyone does that, if you don't take it too seriously. I get many laughs out of this site from responses like that.
Anyway, I would've recommended Halo Reach or LBP2, but how can I even do that when you didn't even let us know what systems you were shopping for too? See the point of everyone's mean responses? Hope that helps a little.
