I wondered today, if something I've always wanted to see in a Civ Game, might at last be possible: A different leader for each era of a civ, with varying bonuses, unique units, etc. The reason I thought this might be possible is after I saw Gedemon's new YNAEMP and saw the possibility of adding something like 50 Civs in the game at once. It'd be a lot of work, and one would have to get pretty creative to find leaders for all eras for some civs. I imagine it would have to be a scenario as well, rather than mod for standard games. Still, it'd be epic to play a Europe scenario, starting out with Roman-era leaders that change over time. Of course, although I'm familiar with XML editing, LUA is a mystery to me, though it seems within the realms of possibility to trigger a 'civ change' upon reaching a certain era, which changes you from the old leader to the new one. So, is this idea plausible, once the mod tools are released?
