Summary: I'm a bigger fan of the first Sports Champions because the Disc Golf is my favorite game to play. However, bowling on SC2 is really fun too. My 8-year-old is a big fan of the boxing game. The one thing SC2 has that's better than the first is the calibration. It's much easier for SC2.
Summary: Sports champion is a great work out game where you really have to move to get things going. You can have a great time playing while your working out. You don't even realize how much you move while you play and that is a good thing.
