The slopes map is amazing. Brings a good feeling to heart when playing blockland there, but I could never find any use for it myself since the terrain maps look so off when there's a build on it. As for interiors, it makes you feel like a lego which I think is important for the blockland concept. I'm not a coder or mapper so I don't understand completely how it restricts any development for the game, but the developers say it does so it's a good thing they're removing it. We're all ingenious and will find really cool ways to take advantage of the new changes that might outweigh the removal of terrains.
