While I agree the Wii can do much more with a bowling game I haven't seen one positive review for Pinbusters.
First off its only $20 so right there is worth a puchase.
Its definitly more difficult than wii sports. My 3 yeard could bowl a 200 in wii sports but only around 110 with Pinbusters.
The ball in wii sports seemed to drift torawrds the pins. Pinbusters won't do that.
Graphics are a smidge better in Pinbusters.
The only thing I dislike it the same ole comments from each bowler and the replays you have to skip after each shot.
