It's fun and it's free. Whats not to like?
Gameplay: 8. A very simple game. All the games are very easy to play. Anyone can play it so if you've got friends over it's great. Games like boxing and tennis require two Wiimotes but the rest you can share one wiimote which means multiplayer is good but not as great as games like Warioware.
Graphics: 7. Nothing much I can say about the graphics in this game. The graphics are very simple but also quite clean. It doesn't have great graphics but it's nice to look at.
Sound: 7. Sound's nothing special. It's simple music and sounds are easy on the ears. Not too bad but not great
Value: 10. It's FREE unless you live in Japan but I really don't think so
Tilt: I liked the game, it was quite fun. I play it all the time with friends and relatives but If I've got no one to play with then I don't play it. It's not bad for a free game, it's like a demo so you get used to the Wii.
I'm pretty sure everyone with a wii has this game so I'm not going to bother recommending this game to you but if you're in Japan and you would like to get a sports game, this game ain't bad.
