So back when Age of Empires, Rise of Rome came out, I also learnt about Carthage.
I loved Hannibal, and how he could have destroyed Rome.
So about 15 years ago, during 7th edition, when we could take 2 steam tanks in a 2000 point list, I decided that my 2 steam tanks, would both be my elephants. I wanted cavalry and infantry, and no magic. I made my Carthaginean army, and had a lot of success with it.
But I never painted them - well, I painted a unit of spearmen, and that was it. But I had the models (or should I say kitbashes) in mind. I wanted them to completely unique, but I also wanted them to be mainly using GW minis. In the Warhammer world, Carthage would be part of Araby, rather than the Southlands.
Anyway, here are sample painted models for a few of the main units (Knights, Light Cavalry, Spearmen and Greatswords). I haven't finished converting / painting my elephants yet....
Knight
Camel Rider (Outrider - needs repeater handgun added)
Infantry (Spearman and Greatsword)
Warrior Priest
