Maybe it's a bit early for such a question during EA, but I'm looking around now that the release of civ6 DLL is officially not currently planned.
If it's similar to Offworld Trading Company I suppose we'll have data (XML) and scripts (DLL) fully open
, but I can't find anything about the art assets (icons, 3D models, sound, ...)
So simple question, will there be a way to add new assets (units & animations, buildings, ...) in the game at some point ?
