Well.. Back to Skyrim, Battlefield 3, Halo CEA, and Gears of War 3. And the first three Halos. Gaming industry has gone to -blam!-. Hell, I played Halo 4 for a week, now I'd rather play Fallout 3 than Halo 4. In fact that's what I have been doing.
Anyway, Halo 4 is a good, fun game... With no replay value. It's not competitive in any shape or form though, which is where your diehard, MLG, fans will come from. Halo's competitive community has been told to -blam!- themselves, it happened in Reach, but Reach had about 3 problems (in multiplayer at least), Halo 4 has many, many... Many more.
