Hey the only thing the PS3 is good for is blue ray.... better off getting a PS3 a a blue ray player since you can actually play games on it... other than that people who have spent the money on it call it the $500 paper weight...lol
Not that many games have been developed for it yet, and the ones that have suck....
Engine swaps in Forza 2 are limited within manufacturers... you can only swap within the same brand. BMW has had very strict rules regarding their vehicles on games, why are you able to do it on some PC simulator, and not on a console sim, might have to do with simple licensing or MONEY!... I do know that lots of manufacturers don't want to have their cars look vulnerable to damage or whatever, so they restrict the amount of damage a car can show on these games as well. Especially if the word simulator is in there... I don't think they mind when it is on an Arcade game series like NFS...even then those hardly show any damage....
