i have a ps2 and i got street 2 a while back for $30 or so. i have never played it on xbox, but i really enjoy playing it on my playstation. it is really fun, and if you have played the first one ( i dont know if it came out on the xbox). in 2, you can unlock tons more tricks and dunks and shit like that and it is hella fun playing with your buddies. the "story" mode is really fun too, but it can be challenging. it is also fun to create a player and throw down with the best of 'em.
thanks,
