Microsoft has kicked off a new promotion today, thanking its fans with a laundry list of discounts on a wide variety of content. Some of the highlights include reduced prices on Xbox Live Arcade titles such as Super Meat Boy and Magic the Gathering: Duels of the Planeswalkers 2012 for 400MS points ($5) a piece, and much more.

Also included in the sale are DLC packs for a variety of games, including Assassin's Creed Brotherhood, and even Games on Demand titles. A full list of deals is available on Larry 'Major Nelson' Hryb's blog.

Gamers without Xbox Live Gold can "upgrade" to 12 months of the service for 33% off the regular price. According to Major Nelson, more deals are planned for both Black Friday and Cyber Monday. Of course, promotions may differ based on your region, so double-check those prices before you click "Buy."
