One idea(you can see this in action on Bushidos server)
Is one i started using a while ago on a server i wont name.
What you do is make one basic house, and then duplicate it to make neighborhoods.
This is a fairly fun thing to do and provides alternate entertainment in RPG's that can keep newbs from ruining it with constant DMing.
Me and Bushido came up with the idea itself Parallel to each other. I came up with it, and he did also at around the same time.
Feel free to discuss other ideas, concepts and designs to better the Blockland community :D
This topic is here to help people who are having trouble thinking of things to build, and people who need ideas for general blockland things :D
