Slitherine

what is the devs point of view on new campaigns, new world map, factions and units for example plus anything that would go along with making it a complete package? A side question i have successfully added units to the original files but is it possible to use separate files so i don't have to worry about potential mod conflicts with other mods in the future

We encourage all forms of modding.

You can create your mod using separate files - see the Modding Guide document which is included with the game for a brief overview of the process of making a mod which doesn't change the game core files directly. IF you have specific issues, we're happy to respond to those here.
