I'd love to see a mod/game editor for bts similar to what we had in Civ III Conquests. I'm not a programmer, and being married with kids, full time job, I don't have the time to spend hours and hours on end pouring through code I don't understand. I'd love to be able to manipulate pretty much everything from number and type of religions, resources, civics, units, you name it, with an easy to use and understand graphic interface.
