Show HN: Shadowvane – A cross-platform Soulslike MMO (built in Node/Three.js) (playshadowvane.com)

Aesthetically it's a Soulslike, but it plays like a themepark MMO (like WoW). That is, you can queue up for a BG-like experience, there is a 1v1 Arena, and there's an open world with EXP, leveling, etc.

With enough developer-specific demand I would open-source parts or all of it, either as a Three.js-based MMO engine, or some other kind of community driven thing.
