I have created a terrain build that contains the aspects of an RP minigame other than monsters (there are dragons but you can't kill them).
It has:
Mining
Woodcutting
Crafting
Selling
Buying
Exploration (of about 10 64x baseplates)
And most importantly, Falling Bridges
Uses VCE with Varlinks, Multiple IF statements, random vars, basic vars, and basic eventing.
Might use it as an app or something.
