Quick two cents: One thing that's been irking me for the past 2 titles is this odd feeling of emptiness between major structures and points of interests. There have been so many times that I've felt that everything seems so 'neat' and tidy except where somebody places an object that's intentionally not neat and tidy as a little dust sprinkling. Anything doodad/trashwise rarely ever seems to 'pop' out enough, and it looks a bit more of the same with Halo Reach. A perfect example would be the MP map Foundry. when you take out the boxes and such, you notice a bit of trash all over the floor every which way, but it's like this tiny little sprinkling that doesn't ever get kicked up by rockets, SPARTAN/Elite boots, etc (though that's just because of the engine), and doesn't ever pile up much higher than half an inch off the ground at most. And on other maps? Aside from the little areas for trash, most of the pathways that you see are barely cluttered with debris, trash, leftover magazines/casings/fragmenting MG links/what have you, and it's a perfect pathway from point A to B, even on cliffsides and forested areas aside from the designated doodads that stick out like a sore mole with the clean bits (like that rock a SPARTAN walks over in the video. Nice Walk in the Woods reference, btw.). Compare with the center of MW2's MP map Favela, where weeds are sprouting out between the cracks of the streetm there's a million different places and ways that the concrete has been torn apart, and you'd be treading on garbage, plants, cinderblocks if you moved half a foot to the left or right of the tighter paths. Of course, the roads are relatively clean, but even then you can notice the potholes and trash littered everywhere. Though, to be fair, the very first level of Halo 3 was extremely cluttered with shrubbery and the like (mostly shrubbery). Furthermore, we were in a crap-ton of valleys for most of that part of the game, which didn't help me getting similar linear pathing vibes as, say, the Pillar of Autumn. tl;dr: More clutter and messy-mess in general, less exceptions, Bungie. I don't care if Virgil is particularly good at his job.
