Hey guys, this is my DBZ game review for the Wii. 
I will incorporate and base my ratings on the same criterias as IGN.com utilizes.
Presentation(9/10)
IGN: An awesome cel-shaded look, a story mode that covers every saga in the franchise battle for battle, 120 playable fighters, and hours of English/Japanese VO. What more could you ask for?
Me: Like they say, if you have watched the anime on television and want to relive it through the game, you can! It goes through every aspect of the story, including every fights and training periods. Not only is the story good (duh), but even the other options are fun and add a lot to your play time.
Graphics (9/10)
IGN: Player damage, destructible environments, tons of solid character animations and effects, and an overall look that rivals the show. Supports 480p, but no 16:9. Weak.
Me: The graphics are amazing, the look of the cel-shaded characters and environments are truly stunning. When you do blast attacks or any other special moves (Kamekameha) they looks awesome and you really feel the power of those blasts! I just wanted to add that I am comparing this and my other Wii games with my old N64 games so they will obviously look much better, but nonetheless I play games in a 1600×1200 on my computer and I still think the DBZ graphics look sweet!
Sound (8.5/10)
IGN: There’s hours of dialogue for both English and Japanese fans, as well as over 30 music tracks. Some of the sound effects could be better though, and most is rehashed from the previous game.
Me: I agree with the previous statement, but once again since I never played any other version the sound/music is great!
Gameplay (8.5/10)
IGN: The AI is pretty tough, and the combat has gotten a bit better. The added motion control is a definite plus, and basically evens out the fact that the game is a port of the PS2 version.
Me: I just have to start off by saying that anyone who buys or rents this game should first start off by doing the complete practice tutorials! I had originaly just booted up the game and started playing with my girlfriend without any prior knowledge of how things worked and I was quite disapointed in the game after an hour. The next day I decided to go through the tutorial and it was my best decision ever! They clearly explain how everything works and how to successfully do the combos and air attacks etc.
The game is now amazing, I can easily do 10-15hit combos and they are soooo cool to do and watch! I can easily say that this game is worth the purchase!
Lasting Appeal (9/10)
IGN: With an immense story mode covering the whole Dragon Ball lineage, Ultimate Z fighter customization, and all-new tag battles the game is simply huge. A bit More depth in fighting is needed.
Me: They sum things up quite well. I think this is a very complete and in depth game that offers a lot to the player.
