Microsoft has told CNET that at least 2 million Xbox Live users logged into Facebook through Xbox 360 in the week since the two services were integrated, and that half a million Last.fm accounts were created in the first 24 hours of availability.

No figures have been released on Twitter use through 360, but according to a rep, there have been “tweets from nearly every market where we have Xbox Live.”

A tenth of all Live users have accessed Facebook through 360 in a week? Amazing scenes.

video game adaptation starring Mark Wahlberg, shot up an easy win at the box office, even as two of the weekend’s other new releases — The Secret Life of Bees and W. — performed nicely, finishing in line with their respective estimates.

The No. 1 action flick grossed $18 million from Friday through Sunday. Although not quite on par with the debut totals of some other game-based movies, like the most recent Resident Evil films, which blew away more than $23 mil in their premieres, Max Payne’s premiere number is a marked improvement on the first-weekend sums of Wahlberg’s previous two gun-totin’ flicks, last fall’s cop drama We Own the Night ($10.8 mil) and early 2007’s Shooter ($14.5 mil). And here’s another sort of backhanded compliment: It’s a good thing the movie earned as much as it did this weekend, for its lamentable CinemaScore grade of C portends a limited audience in the coming weeks.

A day after confirming downloadable Xbox games for 360, Microsoft says “there are some known issues” with the games including choppy visuals, lack of additional content, and even system crashing.

“We got issues.”

According to Xbox.com, “there are also some issues unique to specific game titles,” such as frame rate 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 Dec. 4, Xbox Originals come bundled with the upcoming Xbox 360 update on the same day. Originals cost $15 (1200 MS points).

Additionally, Xbox Live (which turns five on Thursday) surpassed the 8 million member mark — the most of any online console community. In commemoration, Microsoft is offering a free Xbox Live Arcade download between 12:01 a.m. PST on Nov. 15 and 11:59 p.m. PST on Nov. 16. Furthermore, every active member who joined the service in 2002 will receive 500 MS Points for free.
