There's a poker game up on marketplace for Xbox live arcade wich is free if you download before sometime friday. Since the time stated for me doesnt match the time in the US, just make sure you download before friday September 25th. After 48hrs of it's release on marketplace the game will cost 800 points.
I'm not into poker games but since it's free...and there's a cam function for the upcoming webcam for the 360, you never know what it might come in handy for...
If only there were more female gamers...
