At $39.99 I would have bought it, but I missed the deal. Trying it out this weekend, and while I like it FAR better than the PC game, the repetitive gameplay (in early levels at least) leaves me a little cold to it - don't know if I'll care much to follow it through for long.
Still, it is an interesting use of the Wiimotes, and the controllers respond well. A solid, and certainly, different third party offering that's for sure.
