Available as a free download via Xbox Live and Games for Windows Live, Microsoft has rolled out its Game Room virtual arcade – but not without some issues. The service was revealed at CES in January and launched this morning with around 30 classic arcade and console games (full list after the break), but it could eventually host 1,000 or more.

The games are purchasable with Microsoft points, and come in a couple different flavors. For 240 Microsoft Points (or $3) you can buy the titles solely for the Xbox 360 or PC, and 400 MS Points ($5) gets you a copy for both platforms. There is also a single-credit play option for 40 MS Points ($0.50), along with free timed demos.

Unfortunately, today's release wasn't a smooth one, with gamers complaining that they were unable to enter the online arcade. The Xbox 360 edition reportedly froze during loading, and some folks couldn't get the PC version to install at all. An Xbox Live worker quickly noted that the problem was being addressed, and later said it was fixed.
