Microsoft is throwing a House Party on Xbox LIVE in February and perhaps they are bringing several new games to the two Xbox 360 and Windows Phone 7 including the PC classic Torchlight in an HD remake of Beyond Good and Evil together with Hard Corps Uprising.
The announcement of the House Party promotion came following your Microsoft CES keynote with promises to kick rid of it on February 16. Hard Corps Rising is definitely the first game check here but no schedule was presented with as to in the event the rest are going to be released. Presumably it are going to be one or two games each week over a month-long period and include some other kind of incentive to buy all of the games like previous promotions.
These would be the games in line with a Microsoft blog post.
