The level design isn't anything to write home about - what the new DmC has over the old ones is that it doesn't reuse areas over and over and over again. I think that DMC3 has, wedged between the recycled corridors and arenas, more unique rooms which show off the design and aesthetic flair of that team (some of the end game areas are conceptually or visually similar to DmC's core bag of tricks). The exploded environments in DmC's limbo are a neat gimmick but they apply that idea to almost every area in the game which is a bit numbing.
My sentiments EXACTLY. Thank you.
