I don't. It's not safe to assume much of the game.
When quoting someone, it is important to include their full sentence. Notice that my statement was a conditional one. If the levels are indeed randomized, then I think it's safe to assume that the level design in the game will suck. It is irrelevant if the randomization occurs only once. Random levels = no planning, no forethought. Just a bunch of random segments thrown together. Good level design requires a skilled level designer, not a random map generator.
