I described this in another forum here, but basically I'd like a mod that would enable me to design my own civilizations & traits on the fly, choosing UA, UU, UB from lists of choices and leaders and Leader traits/abilities from another list. Probably best if you could design the leaders separately and bring them in to combine with civ traits you select. You can do this in most 4X space games and some fantasy games, so why not in Civ. Mind you, I know you can use existing modded civs and add them but what I'm thinking of is an easy way for non-modders to create their own civs and leaders simply and easily, then incorporate them into the game.
