I thought the whole attraction of the arcade version of this game was that you could actually swing a hammer at the moles physically hit the cheeky chapies hence dispensing of some of that built up aggression that we all seem to be carrying around these days! GRRRRRR. I suppose the same effect could be achieved with the mouse but as things get more frantic you might loose the plot a bit and smash your mouse in to many little pieces. Of course it could also help kids or for that matter aldults to learn how to manipulate the mouse better but I think for those who like to really get in to games (yours truly) then maybe you should pull out that old busted mouse you had with your old IBM compatible PC. Otherwise you may be unnecessarily forking out quite a bit! I needed a new mouse anyway.
Pros: Tests your reflexes Help you learn to control the mouse Something to do with any old mice you have
Cons: Doesn't let you physically hit anything
