I've been playing Bully Scholarship Edition on 360. I never got to play the game back on PS2, enjoying it very much, so much so in fact that it's probably one of the best Rockstar games I've played, I mean, I like it a lot better than GTA4. Or maybe I did play it back then.. I really can't remember, it seems familiar sometimes but for the most part it's a big blank to me. Maybe I rented it or something.
Anywho, for $15 it's basically a full GTA style game made by Rockstar themselves, but with a different theme/setting/much less "serious", I recommend it to anyone who hasn't played it before.
