“The markdown-first approach means we can use Git for version control on our entire game world. No vendor lock-in, no proprietary formats.”
Marcus Rivera
Technical Director at Placeholder Games
“We went from scattered Google Docs to a unified world bible in a weekend. The entity system just makes sense for game development.”
