Watched the gametrailers review.
Seems like the online has serious problems. Hopefully the Wii U verison will have those resolves.
A weird thing though, it mentioned the Mii fighters as not being really important besides creating famous people, and didn't even mention customizable B moves. Which IMO, is in the top 2 or 3 for most important features.
We wonder why devs don't offer more options for customizable this or that....but the general reception for Mii Fighters and customizable movesets seems to be the answer. Which is a little annoying.
