Implemented limited modding support as more of an integration test between the game, steam, and the actual back end data. If this works well I can expand it to incorporate more values and features in the future! Here is a link to the workshop page where you can browse and sub to other peoples mods. https://steamcommunity.com/app/3337380/workshop/
Mods can be accessed in game from the main menu and uploaded from local files to steam.
I also put together a little tutorial on how to create mods and the stuff that is currently available (currently only overrides for unit stats, heroes and faction bonuses)

Obviously custom units are the biggest moding request so will think more for a solution to that, the current problem is that I use a paid 3rd party tool since Unity does not support animations for ECS. The tool is like $25 but I’d hate to have it as a requirement for making custom units so I need to see if there is someway I can work around it, and maybe make a converter.
