Microsoft has confirmed the release schedule for the Xbox LIVE Arcade House Party which begins on February 16 with Konami's Hard Corps: Uprising.
February 16: Hard Corps: Uprising, 1200 Microsoft Points
February 23: Bejeweled Blitz, 800 Microsoft Points
March 2: Beyond Good & Evil HD, 800 Microsoft Points
March 9: Torchlight, 1200 Microsoft Points
March 16: Full House Poker, 800 Microsoft Points
There doesn't appear to be any associated promotion - buy x number of games and get x number of points back - but that's a pretty good line-up with some very reasonable pricing too. Beyond Good & Evil HD at only 800 MS Points stands out as great value.
