OMG! This set is AMAZING! It is packed with pages upon pages of some of the best artwork imaginable. The graphics and textures are better than any of this type I have seen. I printed of a few of the pages, and was so impressed, I had to print them all (and some like the hallways) several times.
There were a few things that I personally didn't care for. There was no consistency between the tiles. Some have 1" squares, and others didn't. The rooms were various sizes, but they don't seem to blend. I would have preferred the rooms been 5"x5", for example, with wallways and passages connected to the rooms themselves. This way, you could build a solid floor, and not have rooms of various sizes.
The biggest issue for me was the lack of a natural flow of the pieces. When you lay them on the table, it looks like beautiful rooms just scattered around. The lack a blending is disturbing, however, the artwork is so good, that you can't complain.
If some pieces are added (like more flexible corridors and hallways) in future sets, I could easily see myself purchasing the entire collection of these tiles.
