i can't play the "storm" versions. they're so different than the original ultimate ninja series.. i prefer the side-scrolling.
I only played the first Ultimate Ninja in the PS2 before Generations on 360, idk why... But I don't really enjoy the game that much. Kid Naruto/Sasuke are so overpowered lol.
I'd take the Clash Of Ninja series anytime over Generations, doesn't matter if they have less characters and i'll never be able to play as Kimimaro, they have a simpler yet deep gameplay, which that's what I love from those games.
