How about inviting Michael Phelps and his tiny speedo in your living room or bedroom !? It will be possible starting June 2011, thanx to the Xbox 360!
"The better stroke technique you have, the faster you go,"
- Michael Phelps
Sounds like a best seller to me ;-)
Phelps' techniques were captured with special high-speed, high-definition cameras for incorporation into the game. "It's all based on moves and actual strokes," he says. "They're trying to pretty much make my stroke look as close as possible in the game as it is in person." In addition to recruiting players to his game, Phelps also hopes that some might dive into the actual sport. "A goal of mine since I started was really to grow the sport of swimming, and having the ability to come up with a swimming game, it shows that my goal is actually occurring." [source]
