Carthage's wealth was not an attribute of Hannibal's leadership though, but I see where you're coming from.
And, as far as War Elephants are concerned, if it's really that much of an issue, I also created the Numidian Mercenary as a secondary option. But it would be no different than replacing the spearman.
Personally I believe the War Elephants, while different, give some personality to the Civilization. Because there are already many Civilizations out, but none of them have a unique unit of the elephants. And, does any other Civilization come to mind concerning unique war elephants rather than Carthage?
I'd be glad to help. If you want any graphics in particular to be used during the installation, I'd be glad to use them.
Oh, concerning the Carthage mod. Would you like to start a new thread with our combined project? I would prefer that rather than just updating my mod with the leaderhead.
Also, do you plan on doing a Korean civ?
If so, I'm just about to release mine tonight, and if you'd like to contribute in some way I'd be glad to have your assistance.
