Following the success of Facebook game FIFA Superstars, EA today finally launched the much aniticipated Madden Superstars. Coming from a new partnership for Facebook games between EA and Playfish, the game is a team management sim that includes game modes like season mode and the ability to play against other Facebook users' rosters. You can either work through normal gameplay free to get upgrades or move faster by purchasing items through microtransactions a la Farmville.
The full press release can be found here. It also includes info on how GameFlow and Online Team Play are being received. Not coincidentally the strategy pad isn't mentioned.
