Legend of Zelda: Twilight Princess for GCN and Wii
The game has great graphics, great music, a wonderful world (Hyrule), and great gameplay. The Wii version uses the remote as a sword. That's one difference between the Wii and GCN versions. The other difference is that Hyrule is mirrored in the GCN version compared to the Wii version. It's kind of confusing if you play one version, and than the other, but it's cool anyway. The dungeons are kind of repetitive with the fact that you delve in and get a new item, and use that item to finish the dungeon, but that's whats called Zelda Theory 101, so it is the point of the game and the series. I rate it 9 out of 10.

Wii Sports for Wii
This game is awesome, the movement of the Wii Remote is utilized very well for each sport, it even really does give you exercise. It includes tennis, baseball, bowling, golf, and boxing. And it's kind of like Brain Age, because it has a mode where it tests your skill in the sports, and gives you a fitness age. I rate it 8 out of 10.
