I bought a 360 for that very reason, Nothing else was out at the time. I started out humbly enough as a master system fan rose through the consoles to Snes accolade. Then i got my feet wet bought a PS2 and stuc with it for ages, My lil bro bought an N64 with golden eye, perfect dark, Conker smash bros etc, and i love nintendos simplistic fun. Perfect example is Super mario Kart. I played it only last week it was on display hooked up to a tv in a game exchange type shop, I'll lbe honest i spent a good hour playing it Just because it was so much fun.
Re PS3 i'll buy one cos of the whole platinum collection i got at home PS3 will inevitably have a new MGS. so thats a bonus. Revolution, Nintendos fun, and cheap so ill most likely get those two consoles in one whack about 6 months after relase.
