Microsoft says "there are some known issues" with the new downloadable games for the Xbox 360, including choppy visuals, lack of additional content, and even problems with systems crashing.

According to Xbox.com, "There are also some issues unique to specific game titles," such as framerate drops in Halo and Fuzion Frenzy, minor flickering in Crimson Skies, random bursts of audio static and texture issues on Fable, and lack of 720p support for Psychonauts.

Confirmed for release on December 4, Xbox Originals come bundled with the upcoming Xbox 360 update on the same day. Originals games, including Halo, will cost £10.

Additionally, Xbox Live (which is five years old today) has surpassed the 8 million member mark - the most of any online console community.
