Looks sweet and I might buy it because I have a crazy project of a really big fantasy castle in mind but I do hope this stuff is better than their houses. I bought them all and they weren't really easy to assemble: precuts that aren't finished, resin windows that don't fit in the rooms, some things that appear on the pics and not there (I hope that won't be the case for the stone part of the fortress walls because I would hate to have to carve them myself).
I have been told that the issues I met with their products disappeared with next batches but I will probably wait for a couple of reviews before jumping on the fortress or buy one or two walls and see what happens.
Good thing with their products is the reasonable price and the light weight.
Jimbibbly: It's fantasy (set in the Kensei world) hence the tower looking a bit like a temple.
