This game is amazingly fun. For starters the sports are very varied, you have Table Tennis, Disc Golf, Gladiator Duelling, Archery, Bocce and Volleyball.
All games are different and deadly accurate. I believe Table Tennis demonstrates this best, you can do slice shots, power shots, back hands and so much more. I'm not a pro table tennis player by any means, but this game makes me feel like I am. Bronze trophy for Table Tennis is easy to start with but AI becomes progressively harder making winning the trophy ultimately -- rewarding.
And I believe this is the main focus of Sports Champions. Everything about it is so rewarding. Because if you do a poor toss of the disc in Disc Golf then you feel bad but if you do a perfect throw and get it in 1 shot or less you feel so rewarded.
It's got the same reward:difficulty ratio as the real sport.
Oh, and Gladiator Duelling... BE prepared to get a great work out. You feel you have to block the strikes with your shield and you put so much power into swinging the sword at your opponent. This is a FAR FAR cry from the Wii "Waggle to win". This is PLAY and PLAY WELL to win.
