One game I enjoyed about the Xbox 360 was the highly entertaining and liberal to play 1 vs. 100. It was fun by sitting, answer some random questions, earn achievements and maybe get called through to stage to win some actual life prizes, and it also was cost-free. The game went away several months back but, the following free multiplayer type game is incorporated in the works.
Full House Poker currently is in the beta phase over in Australia, and possesses gotten the rating of G, although it at some point had a T rating with the gambling aspect of the game. Because it's exactly the beta, were a little away from finding the actual game to learn but the idea that it's being beta tested is a great thing.
I'm not much of a huge poker fan but I will play several hands, and this also is one game I fully consider playing if this drops, which I would estimate have been around more info in 2011.
