Why Nintendo is Awesome 

The Nintendo Revolution was already on my "must buy" list the moment it is released. New Zelda game, probably new Mario Kart, and probably new Mario Party with the cool-ass Nintendo controller. Plus, it's backwards compatible with the Gamecube, so I can keep playing all my games and finally finish Wind Waker and Eternal Darkness.
Then they announced that it would be able to download and play Nintendo games like old school Super Mario 3 and Tecmo Bowl.

Then they announced that it would be able to download and play Super NES games like Super Mario Kart and Ken Griffey Baseball.

Then they announced that it would be able to download and play Nintendo 64 games like Mario 64, Mario Kart 64, and Goldeneye.

So, at launch, you'd spend $200 and get a system that could play Revoluion games, Gamecube games, N64 games, SNES games, and NES games. That rocks, especially if the old games are like $1.99 or something.

Yesterday, at GDC, Nintendo announced that the Revolution would also play Sega Genesis games and TurboGrafix 16 games. Basically, almost any game I played as a kid up through college is going to be available to me. That, my friends, rocks. Who needs Grand Theft Auto or ridiculous life-like graphics when I get get a bunch of people together to play 3 different versions of Mario Kart?
