You create a team using real major league players from 1907 or 2007 (the more years will be added over time). To start you are given 40 players, displayed as baseball cards. The game will auto-create a team for you based on your best players, or you can go in and tweak each player individually, including setting the pitching roster and batting order. You then challenge other teams. If they accept, the game is played.best way to experience it is to try it out of course, and techcrunch has the info on a code you can use to get into the beta, so hop to it.
let me add my own review: this is awesome, this is totally awesome, this is the coolest concept ever and a great new direction for fantasy games, and i'm not sure if i'd actually spend money on it, but it is awesome.
