We are aware that modding is a really big thing and many games would have vanished quickly without mods. Also, some of the greatest games started out as mods. Some examples for great modding are civ, total war, half-life, skyrim and mount and blade.
Thing is, that our resources are really tight and we have to finish the game above all else so there wont be explicit modability during the early access. However, be assured that it is high on our list!
