I thought it looked pretty good so I downloaded it yesterday. It is a lot of fun "at first!!!", I got bored with it 30 minutes in. Give me some options my gosh! 4 courses? 4!!! Let me unlock new one's, or make my own. I'd rather spend 40+ on a game with options via SSBB or Mario Galaxy(Which I have already).
It would be good game if there was some substance to it. Mabye I'm missing something? If so let me know, because I really don't see this being an actual game.
