I have nothing against dancing games. (Secretly, I like them quite a bit.)
I am a Star Wars fan who doesn't think that the series needs to be taken seriously all the time. People complain about the prequels, but they really weren't that bad.
But this? No. I don't want this. I don't want to see YouTube links and definitely don't want to play it. If real music tracks were used instead of weak-ass revisions, I'd be ok. [Edit: thinking about it more, this is what bugs me. I don't really care about the Star Wars part, but hate seeing the music one-offs. What possible incentive do I have to pick this over Dance Central?] If it made meaningful use of the Star Wars license, I'd be ok. But what I just saw? No.
Presumably this is only part of the game and the on-rails stuff is also still included? Are there other game modes that might save this travesty?
