Does this mean that games cant be moddable?

is definitely the kind of thing we’d like to see! Migrating content import and asset packaging away from the editor-only side of the project would actually solve a lot of our problems. It’s not a catch-all for everyone though - our game is largely procedural, so we only really need content import and some scripting ability to incorporate basic modding. I can easily see other games needing much more though.
