Pinwheel is a new MUD engine built entirely in Node with ES6. It doesn't require an external database and can be quickly brought online for players. Built from on Shawn Biddle's Ranvier, Pinwheel is a rewrite of the engine and its bundles into a highly opinionated format. Pinwheel makes decisions about world persistence and core features so creators can focus on building their worlds. I later restarted this project as zigmud.
