Good point. I'm sure it will be -- it's unity based and there are plenty of mods for unity games.
Yeah, the biggest thing missing from the SRD is 1) the Forgotten Realms lore and 2) the battlemaster
So I could see someone modding the battlemaster. Having said that and while I'll always prefer Faerun to other settings I think devs have done a nice job within the limits of SRD. Hopefully they will get a crack at full license someday.
