You should make a 24/7 Themed Freebuild with Terrain Freebuild Rules. That would be much more interesting.
(Maybe city or pirate, for example.)
I would if I knew how. If you want to help me set it up I could definitely do that.
Doing that is very simple. Just follow these two steps/rules:
1. Set up some sort of spawn/center that tells people what the theme and terrain rules are.
2. Use
this add-on to enforce building on 64x64 base plates aligned with the existing grid.
Although, if you do that, it will honestly be more of a block party rather than a free build.
