You do yeah, but compared to the character creator of say Soul Calibur V or APB it just pales in comparison.
Honestly if I could condense all my wants for a WiiU Dragon Ball game, it would be a fighting style VERY similar to Tenkaichi 3, improved, faster, and more defence orientated (trust me) with a killer RPG story mode with detailed environments you can walk around and interact with.
Most importantly though would be the flow of the game between these two. Imagine if instead of stages, you had one stage that was a huge world map (think Just Cause 2). So in this example, you're Goku right, going through a forest or something, and bandits or martial arts rouges or someone jumps out and attacks you. Similar to Zelda, you would lock on to them after free roaming around in 3D, and it would be like a Tenkaichi battle. When you're done, he poses for victory and stat increases/level ups occur, and the camera swings right back around behind Goku where you can just keep going.
Nothing I've suggested is out of the question, it's all possible, especially on the WiiU.
Or instead of being Goku, maybe you can be your created fighter.
But they need to improve the fighter creation.
I can be the Black Super Saiyan 4!!!
