just finished assembling my first block. The detail on these things is amazing, special mention must be given to the cute little three pin plug sockets on the interior walls & the swinging doors. The kit goes together very easily but everything is a nice tight fit. I can't wait to fill a gaming table with a full C.A.S.Hstak complex. It is by far the nicest piece of terrain I've ever assembled. Keep up the good work guys, I can't wait to see what you come up with next... Maybe some interior furniture???
