I bought this along with the corridors pack. Quality is great, the artwork really excels in this one. Slightly disappointed that it's not truly modular - components can be rotated and fitted together in lots of combinations, but modding is really difficult due to a few aesthetic decisions. For example, lots of light sources which mean overlapping can look weird, and the modular room tiles have an "edging strip" design, so if you want to layer the blank, corner and straight wall tiles to make large rooms, you get a really awkward floor pattern that doesn't quite work. Still a great set, just not quite as customizable as I'd hoped compared to the basic dungeon set. And I know this gets said a million times, but what I wouldn't give for a pack of compatible doors/furniture for VTT purposes...
