#5 Tom Clancy's Rainbow Six 3: Black Arrow - [ Xbox ]
Okay, the single player mode just sucked. The gameplay was linear, enemy A.I. was predictable, and the visuals were just okay. The multiplayer mode really carried this game to superstardom. You could pick-and-choose some very cool and authentic weaponry to use while hunting for opponents in fun and well-designed urban environments. Fortunately, it was online play that saved Black Arrow's butt.
