Today only: buy one of these Xbox Live games, get another copy for a friend

Amazon is running an Xbox Live promotion that guarantees awesome multiplayer fun in one of three games, unless you don't have any friends, or, uh, don't like these games. Okay, maybe it encourages awesome multiplayer fun. Today, if you purchase Super Puzzle Fighter II Turbo, Street Fighter II' Hyper Fighting, or Uno from Amazon, you'll receive a code for another download of the same game, to give to a second player.

You haven't lived until you've unlocked the secret Dan character in Puzzle Fighter and experienced the kind of defeat that comes from only being able to drop red blocks on your opponent's screen. It's a thrilling way to ... lose spectacularly.
