Or is the ability to mod in this game less then other games in this genre? I'd like to see a forum for people interested in developing mods... If the game completely lacks the potential to do anything cool, perhaps Divinity 3 will have more modding features? As a lot of upcoming competition in this genre is going to have modding support or official toolsets... Two worlds 2, Hunted, Torclight 2, Grim Dawm Dungeon Siege 3, Witcher 2, Neverwinter Nights Reborn, Dragon Age 2 are those of which so far that have been announced.
It would be possible to mod it if the game could use the mods without having to replace the default resources. Once that is in place then it is a matter of working out the file forms and making tools* for modding.
* which would likely need to be simple, but there are things (such as items) that seem like it would not be too hard to make a tool for.
