There are a bunch of features Reach bad that are gone, and should be in (right stick to navigate scoreboard, fine adjustment in Forge, etc.), yeah. Definitely trumped by Halo 4 on the whole, though. Imo. --- I am a fan of My Little Pony. You do not have to watch My Little Pony.
I saw someone say the UI was better in Reach. I've heard this before and I disagree. Maybe its because I'm new, but Reach had like, a bajillion game modes... And doesn't bother to explain any of them to you. That IMO is a fail of an interface right there. --- -This post is in no way shape or form a TOS violation-
Firefight. Seriously. Where did this go? SPOPs doesn't count.
Lack of perks.
Online wasn't nearly as laggy for me.
I also thought the design of the armor was more interesting or functional looking. The armor in this game has a very anime look to it.
I also found the campaign to be much more fun to play. We didn't have the "player is the legendary guy that never loses" thing going for us. --- GT: HiPOJaK I'm so happy I could just tear out your intestines and strangle you with them! -Sheogorath
