def jam vendetta 

BEST. GAME. EVER!!! I love it! A wrestling game with Ludacris, WC, Method Man, Redman, Scarface, Joe Budden, DMX, Capone, and my personal favorite, N.O.R.E . It's so bad, it's good. Super-cheesy dialogue, with bitch-fights through out. Beware of playstation thumb, though.

Def Jam Vendetta...I could play it for DAYS!
