Taking a page off of services like Steam and Direct2Drive, Microsoft is hoping to get more people notice its recently launched 'Games on Demand' service by offering deep discounts on premium titles. Starting today and all the way through Monday, March 1st, you'll be able to pick up the critically acclaimed Batman: Arkham Asylum for 75% off its regular $49.99 price – that's just $12.49.
The company is promising similar deals every weekend throughout the month of March. The game and the deal will be announced by Microsoft's Xbox division voice, Larry "Major Nelson" Hryb, through his Twitter account. There are only thirteen titles on the service right now, so you might want to check them out and hope you favorite is up for next week's deal.
Other sales running this weekend include all of the Spellforce games selling for 75% off via Steam, several strategy games on Direct2Drive with discounts ranging from 25% up to 75%, and a handful of titles going for as little as $4.99 on Impulse.
