Halo gaming for PC is a relatively untapped market for Microsoft. The last Halo game that was available on PC was Halo 2, which sold incredibly well on PC as well as the original Xbox. Porting Halo 3, 4 and 5 which many Halo players consider to be the best multiplayer game in the Halo series, would bring in much more revenue for Microsoft than it would cost to make a PC version of the game. We encourage you to bring Halo 3, 4 and 5 to the PC not only for PC gamers who love Halo, but also for the future success of the Halo series altogether.
