There's an insane sale on Xbox games right now - these are the best deals

The Xbox One has a major advantage over the PlayStation 4 in one crucial way: It's able to play a vast library of games from the Xbox 360. Not just any old games, either - games like "Mass Effect," and "Red Dead Redemption."

Right now, for a full week, Microsoft is offering a massive selection of those Xbox 360 games at ridiculous discounts. The sale is happening exclusively online, for digital versions of the games, on Microsoft's XBL marketplace. Some of these games are going for less than $2.

It's the latest sign that Microsoft is getting more serious about sales for the Xbox Live platform as it adapts and reacts to the approach taken by online markets such as Steam, which regularly have big sales.

You can check out the absurdly long list of more than 200 titles here, or you can peruse the choice cuts and best discounts that we've selected below.
