Halo as a whole is my favorite FPS for two reasons. The epic campaign, and the competitive nature of the game compared to other FPS games. In comparison to other FPS games most of the competitive playlists throughout the series are very balanced and require more than just a spray and pray mentality. In a nutshell that is it. Unfortunately most gamers these days do not want to have to get good at a game. They want to be able to pick it up, start with the most bad ass gun in the game, and fire from the hip so to speak.
