I picked up Simpsons Hit and Run today for Gamecube. Its the first good Simpsons game since that old school arcade one. Its bascially GTA3 but in springfield. You can drive anywhere and steal any cars and you do mssions for people. Tons of bonus stuff, like hidden cards with info from the show, minigames, and costumes (its even got homer in the mumu) There is references and places from like every episode. its on PS2 and X box too its not the best, GTA is way better, but its cool if your a simpsons fan.
Heh, I got the 'hit and run' baseball cap a while back through a local game shop - it's pretty damn cool, on the front it's got the 'diamond' yellow sign with Homer, Marge, Bart, and Lisa running on it... Glad to know they've brought something out that's worth a damn... Bart vs. the Space Mutants and it's subsequent sequels/spinoffs kinda let me down...
