One of the games that may have slipped under the radar for the Xbox 360 is Tetris: The Grand Master Ace. The game was a Japanese launch title and is currently not available in North America. That's not to stop the game from being a nice little puzzle that's gotten a good import user review via GameSpot. From the review: "Tetris: The Grand Master Ace is a great little game, with a nicely thought out online mode, which encourages having fun with others even if your not playing versus. Trying to unlock the achievements add to the addictiveness of a game which already was very hard to put down."
Combine the classic gameplay of Tetris with Xbox Live? I'm in. Now if we can only get a US port.
