And here is the other thing. Not everyone plays or cares about MLG. I really wish some of the"top" Halo fans would stop complaining, look at things other than competition, and actually put forth an effort to play the game as a whole. I think Halo 4 is a step in the right direction, but yet again, the developers of the last two games have done a half-hazard job. Reach was only fun after better maps were made and were forged and TU happened (it made it better, fixed problems). Bungie did a bad job with Reach, best part: forge. 343i brought Halo back in the right direction, but made some huge mistakes.
Forge, although easier to use and a nicer appearance, is missing a larger forge world and the minor tweak controls. 343i also loved the DMR too much. In TU in Reach is became much better, not only useable, but worth using. In Halo 4, 343i made it the best starting weapon. The DMR is too accurate and powerful. The BR is harder to use against it. The carbine has become the needle rifle, lots of bloom after a couple shots. In Halo 3, the carbine was useable for most people, but was splendid in the hands of someone who could use it well. Game settings are less customizable than before (not a lot, but enough to be noticed) I think weapon drops are great and I love personal ordinance, but believe that more regular ordinance drops, and fewer personal drops would be better.
Halo 3 is still my favorite, but Halo 4 could end up being my favorite if some simple changes are made. I think Halo 3 campaign was the best of the Halo series and that 3 multiplayer was what fans needed.
