I don't like Halo for two simple reasons.
1. The story mode is boring and not even a challenge on legendary, it's not hard at all. I don't know what's the problem. You have enough time to take down an enemy, one by one, but yet I see persons rush in with a room full of enemies and then afterwards ask themselves why they died.
2. I suck at playing FPS games online on a console simple because I'm 1000x better with having a mouse and keyboard below my hands and not a controller.
same goes for other fps games
