Wow, is this really true? I’m definitely with @Left_Empty on this one. I prefer Halo 1 by a lot. And then Halo 4 after that, tied with Halo 3: ODST and Halo Reach. And then Halo 3 well below that, and Halo 2 at the bottom. Though Halo 2 gets the reprieve from being total garbage by having amazing multiplayer. I played Halo 2 multiplayer second only to the original Halo.
I had no idea Halo 2 and 3’s single player campaign had fans.
