Don't get me wrong, the game isn't horrible, it just doesn't have any intensity. When you start the game, you play in like an easy tournament thing, and it's just boring really. It doesn't really capture playing table tennis for real. The screen is dark and just makes the game that much more boring. I haven't tried the multi-player yet, although I have heard the multi-player is better than the single game. I wouldn't recommend buying this game, because after playing a single match, I turned the game off out of bordum. Rent this and just invite some people over maybe? I don't recommend buying it though.
Rockstar did a pretty good job on this one, my score doesn't really represent the game play. Playing a game against a friend is a blast. Not as fun as the real thing of course, but a nice substitute. Problem is, that's the only time it is fun. The single player game is really lacking in that department.
The characters are okay looking, but games like this really need to let you make you're own character, That would definitely help the fun factor. The game physics on the other hand are pretty sweet. The controls make using those easy as well. So all in all, if you have people who want to play ping pong on the wii, get it. Otherwise, get a better single player game.
