Phet, I'll back you up. It's pretty tough to pick a "best arcade game" but it is certainly right up there. So far it keeps me coming back more than probably any of my other games. I think one of the things that makes it a great game is that the game doesn't go on and on - there's no dying, but it has a hard time limit (with possibly one extension). And then the cabinet - the periscope, the mirror system, the artwork. Hard to beat.
