Very high quality components, and looks stunning when assembled. Bonus points for the modularity. Negatives, the instructions were incomplete - you can figure it out, but seems like a basic expectation on a kit. Also, you need to buy extra components to actually get a staircase or ladder to the second floor, if you care about that level of architecture sense and playability of the space. It still sets a high standard for how terrain can look, is very satisfying to assemble, and cool that you can leave it able to be unstacked to play the interior. A full map of these kits would look phenomenal.
