It's not bad to change, but this looks like a totally different game with "Halo" slapped on the box. There's advancing things forward a few years, and there's going overboard trying to prove you're not bungie. I like being able to change the look of the gun, but it really is trying too hard on the armor. If those are real, the gungnir is the only one that could pass as halo.
I think a bigger complaint is, at least with the several year difference between Reach and H3, there was still a halo "feel" going, which is lost here.
And saying you don't like the look of a skin or design, does not matter if the game is released or not, it's a "looking at" thing, not a "playing it" thing.
Also, what's with the buttplate in hazop?
