ccording to an interview with Next-Gen.biz, Microsoft plans on refining its current library of Xbox Live Arcade titles as well as overhauling its digital-rights management system. Marc Whitten, general manager of Xbox Live, told the site that Microsoft will start culling lower-quality games from its Arcade service. How will games be marked for that dubious honor? The company will use three measurements when making the decision to pull it: First, games must have been available for download for at least 6 months. Then, it has to have a Metacritic rating of lower than 65 and a lower than 6-percent conversion rate (the percentage of people who download the demo and then purchase the full version). Microsoft will provide a three-month notice before pulling titles.

While it sounds like a good idea, we do have a few questions about how it will actually work. Will delisted games still support multiplayer for those who have previously downloaded them? Will people who are transferring their Xbox Live accounts to a new system be able to redownload those games after they’ve been pulled? We’ll let you know when we get the answers to those questions and more.

Finally, in the interview, Whitten mentioned an upcoming tweak to the Xbox 360’s DRM, which could placate certain users. An update coming sometime next month will allow users to download content again (say, if they’re using a replacement console) and be able to access it while offline. Previously, users had to log on to Xbox Live to use that content.

Don’t let that update talk fool you, though. Whitten says Microsoft won’t be releasing a Spring update for the console.
