It does. Hopefully the trailer is holding stuff back. However, I did have fun with the first one, so I'm going to keep my eye on this.
They are most definitely holding stuff back, but then again, if it ain't broke ... keeping things really similar to the first game doesn't have to be a bad thing. I bought this for the Wii U when it was a part of some digital sale, and I had playing it as well.
I don't remember much of it, though. I remember the names of the moves you gained were funny, and there was one which didn't do anything at all, but it still got a special screen after you got it.
