There's a lot of good games for PS3. Devil May Cry 4, Call of Duty 4, Resistance, MGS4, etc. Personally I'm not much of a GTA fan but some of my friends that are say that GTA IV isn't as good as the others (also I really wouldn't recommend Mercenaries 2, I herd it's pretty much a cheap knock-off of GTA). Within the next few months though there's going to be some really amazing games coming out such as Call of Duty 5, Fallout 3, Prince of Persia 4, Resistance 2, etc. Hope this helps.
