Is it possible to mod the rules and distribute it via impulse?
In the journal, frogboy leaved some comments and example about the modding that could be done in elemental. According to the GUI, You can download new maps, tiles and quest.
But originally, they said that elemental would have much more modding capabilities and that you would be able to change the rules throught XML editing or Python coding.
Now maybe this feature is not implemented yet in the interface or maybe these mods will not be available via impulse. Players will have to manually distribute and install the files.
