Bit out of our usual scope, but beggars can't be choosers. Kudos to rhino, who pointed out a news item at Firing Squad detailing another purchase of a gaming company by Microsoft. The company in question is NetGames USA--a bit of background nipped from the full news item:

Microsoft plans to add technology developed by NetGames to select retail games currently in development, including MechWarrior 4: Vengeance, scheduled for release this holiday season. The company will also maintain support for multiplayer games currently utilizing NetGames' technology, such as Unreal Tournament, on Zone.com.

Looks like UT fan's may be feeling a bit of angst about this. They're everywhere!
