Microsoft has announced that eight new titles have been added to its Games for Windows range – Capcom’s Bionic Commando, Eidos’ Conflict: Denied Ops and Tomb Raider: Underworld, Sega’s Space Siege and Empire: Total War, Stardock’s Sins of a Solar Empire, LucasArts’ LEGO Indiana Jones and Microsoft’s own Train Simulator 2.

And in a leaked memo to Microsoft staff, games chief Don Mattrick added: “I am especially excited to continue the progress we have made with Games for Windows.

“In our first year, we’ve delivered to consumers a recognizable brand that communicates quality, fun, consistency and safety, growing from two titles in 2006 to over 60 at CES 2008. In November alone, Games for Windows titles accounted for over 20% of all PC game sales at retail in the US.

“In 2008, we will focus on expanding our brand presence even more, bringing more publishers and titles into Games for Windows, and building Games for Windows Live into the best gaming service for Windows gamers worldwide.”
