Bobby, you fan boy shows what you know as you can get Fallout and Bioshock for PS3... the asker even shows Fallout as a answer. My advice is to tear your eyes from your precious Xbox long enough to learn to read..
Anyways..
1- Resistance 2: Great story, excellent choices of weapons, great range of enemies to test tactics, online co-op is simply amazing and competitive is excellent
2- Fallout 3: Very long, large map, tons of weapons ranging from sledgehammers to mini nuke lauchers, soon to have DLC, nice story, good karma system that unlocks unique paths.
3- LittleBigPlanet: Absolute genius with the story being suitable and enjoyable for all ages, great online range of user created levels and the ability to create your own is nice aswell.
4- Resident Evil 5: Great graphics, fast and furious game play, great range of weapons and unlockables, nice range of enemies and Versus mode is great aswell.
5- Fifa 09: Great gameplay, licensed players and leagues, manager mode is great at 15 seasons long, ultimate team is unique and the idea of having cards as players is cool, good player creation system, large range of game modes.
