I think it may be 2nd best of all Clash of Ninja/GNT games released since the game's release back.

User Rating: 9 | Naruto: Clash of Ninja Revolution 2 WII
Although I haven't seen anywhere near enough videos on EX 2, I believe this game is the second best game to be released in the GNT/Clash of Ninja series. Let me shortly go into GNT4. GNT4 wins over this game in: stages=stage music( 32 different stages= 32 different stage music, many of which are awesome or very good), 3-man cell, character roster is highly controversial, and maybe some other things you'll find out somehow. Revolution 2 has better graphics, wonderful exclusive stage music, wonderful exclusive menu music (when I saw one of the game's first BETA videos released I was upset, the GNT4 VS theme hadn't been added, they released a video with that theme the next month(July), I love the GNT4 VS theme), Kumite Mode (way better than Oboro Mode), wonderful exclusive characters ( 3 of which Japan imported into GNT EX 3 according to rumors), and more. Music is one of the best things that my 2 favorite series (Naruto and Sonic) both have and they probably top a whole lot of other series. I love the Results theme and the ending movie and music of the game. This game tops all of Japan's other games ,besides GNT4, from EX 2 back. America did well. I enjoy the new modes and they increased CPU difficulty. S-rank missions are extremely aggravating, which gives you the biggest challenge in the game probably. I've only been able to beat Neji's with Hokage rank and have attempted few others. There's alot more I'll leave for you readers to discover. Time value is great. Disappointments include no Kimimaro, Third Hokage, and quite a few missing tag team specials. Hope you enjoy the game if you get it. I'm far from beating it, but now that I've figured out how to unlock Awakened Hinata a little over a wekk ago, I'm starting a new, permanent file on this game, and discover everything else I haven't discovered and unlocked, considering I hadn't done too much I'd have trouble with doing again in the files I've deleted.
