I wonder what it would cost to try and do this same thing in Dwarven Forge?

Here was my version. It has bits from a few sets you cannot purchase any longer, but overall the sets would be far more expensive. Having said that, if I were starting over I would use a 3d printer. You could crank something out for a fraction of the price.
I am all about luxury D&D items though. I have to admit I am very tempted to get this. If I had not already run these books a couple of times I might pick it up. Plus, the space, where am I going to cram another piece of terrain that size in the gaming room?
