With my group, we play MoM by only putting out a tile as an investigator advances into the next room. Of course, I'm an old AD&D nerd from the late 70's so I'm quite at ease with house-rules and such. Anyway, by only laying out a tile as an investigator moves into the new room, does add much.
I will admit that I use quite a bit of set up space and prep time to keep the rooms separately stacked with their encounter cards. I've also spent a considerable amount of time coming up with extra "scripts" for the combat cards, and other nice visceral descriptions for the "Nothing of Interest" cards instead of just.....nothing of interest. If any of you came and played at my group with the amount of effort I put into MoM, you wouldn't play anything else. Well, except maybe a role-playing game covering the same theme.
