It's been more than a year since Nintendo released Game Boy Advance -- a much, much more powerful Game Boy with a bigger, color screen and several times more processing power.

Nintendo has sold more than 10 million units of the system worldwide and the number should hit 15 million soon.

Game Boy Advance is backward compatible and plays the thousands of games that were published for the original Game Boy, including such greats as "Tetris," "The Legend of Zelda: Links Awakening," and "Bomberman." But for the most part, Game Boy games have generally ranged from bad to fair. Quantity in this case does not mean quality.
