From what I've seen, TVWP has (or will have) the highest visual quality of any campaigns in the make.
I mean, name me ONE other campaign that 100% supports alpha_envmapping.
I havent seen a lot MT screenies, I have to admit, though.
-edit: TopAce: I'm not a huge fan of posting semi-decent half-done screenshots. I actually dislike the whole idea of too much screenshots and stuff. The TVWP should be something fresh and surprising (like when you first played the retail campaigns), not like something you already know inside-out.
