DF has launched an ambitious Kickstarter to expand their game tile system. This one is a modular City building system. With this 3d terrain system, you can now fight above, on or below the streets of your fantasy cities. It was fully funded in the first 20 minutes, and hit a million dollars in the first week.

If you want the best playable and modular terrain that you can buy, this is it. Join this Kickstarter as once this goes retail, the deals won't be nearly as good.
