I just watched the Mysterium presentation and it looked amazing. I just realized that I actually like the minimalist look the game has without textures. Especially in Gehn's lab on Crater Island. Could there be an option to actually turn off textures in this fashion in the release? Just replace them with the proper colors for the item and leave all of the lighting effects in place?
I have to admit I never particularly thought about that, but you are right. It does look particularly cool. ;}
Side-note: Untextured models could also be used as a performance/debug option for people with slower computers. Textures take up a heck of a lot of memory.
