There is a fairly new sports game that started in the past 6 months called FootballIdentity (the address is simply footballidentity.com). It's basically a turn based soccer sim, where you control a player that you create and play with him in matches twice a week, with others that play in your league.
There's still another week before the start of Season 3 within the game, and the game's userbase has more than doubled since the start of last season.
