Starting on March 19th, Microsoft will begin a promotion called "Days of Arcade" that will see seven new titles added to Xbox Live Arcade in six weeks. Here are the games coming soon to XBLA:

• The Dishwasher: Dead Samurai
• Flock
• Hasbro Family Game Night
• Lode Runner
• Outrun Online Arcade
• Puzzle Quest: Galactrix
• UNO Rush

Note that this isn't the order these games will be released. The only release date revealed was for Hasbro Family Game Night, which will kick off Days of Arcade on March 19th. At least one new game will be added each week and one week will see two XBLA releases.

Last year, Microsoft held a five-week promotion ("Summer of Arcade") in which anyone who played the trial or full versions of the new XBLA titles while logged into Xbox Live was automatically entered into a sweepstakes. Among the prizes for the sweepstakes were an Xbox 360 "Elite" Console, Xbox Live Gold subscription cards, and Microsoft Points. There's no mention of what sort of sweepstakes, if any, Days of Arcade will entail.
