I hear most people like COD 4 a lot more than the new one. I think someone mentioned that the new one is made by a different developer so the things that made COD 4 so awesome arent necessarily going to be present in WAW. I'm not a huge fan of the games but from what I've played it seems like COD4 is kind of the gem amidst the rest of them.
Other game's I'd recommend are GTA 4 (this game will provide you with hours of fun game play and a good story.) It is controversial though so if you or your parents (if you still live at home) dont like all the things that come along with GTA then obviously pass it up. But coming from someone who thought the previous games were way too over rated I'm telling you this is the most fun I've had in a long time. Also Fallout 3 is amazing, Condemned 2 is really fun and possibly one of the cheapest games out for the PS3, also if you never played Bioshock for the 360 thats available on the PS3 as well. And of course lets not forget The Force Unleashed this game looks really good on the PS3.
