Halo 2 was one of the biggest, most epic entries in the series. Its incredible singleplayer story mode and superb multiplayer helped H2 become a huge success in both Xbox and PC. With Microsoft's recently renewed interest for the PC as a gaming platform, bringing Halo 2 again to computers seems perfectly logical. There's a lot of people out there who would be incredibly excited about a PC release for Anniversary 2.

But please, no Vista-esque Windows 8 exclusive!
