Microsoft has added the first batch of new titles to its Games on Demand service over Xbox Live. Among them is Saint's Row 2, a two player co-op title we rather enjoyed last year. The game costs a staggering 3000 , which translated into real world monies is $37.50. Considering you can get the full retail game for $28 (shipping included) I'm not quite sure you want to hop on the On-Demand bandwagon just yet.
But, if price isn't a problem and you just want the downloaded convenience, hit this link to add it to your queue.
Update: Oddly enough, now the link goes to Saint's Row 1, not 2. Also the price has dropped from 3000 points to 2400 points or $30. I swear it was there earlier.
