Indeed I had not the opportunity to play it. But what Im saying is, based on what we can see, theres nothing crazy on believing it seems more similar to Tenkaichi then Budokai. Hopefully there will be a demo to try it out. (Or there is already?)
Does it matter where you preorder? I checked out the official site and realized it was for UK... Then I went to the DBZ site for USA.... and whoa, talk about outdated....
