Well. I ask about desingn the historical units, to create some padron, because there is many representations of punic units, and they aren't the same.
About future Carthage:
Carthage would only survive with several changes in the way of how his people saw him. Would be needed a system change, and the rise of a nation spirit, not a oligarchy club like it was...
Punics are phoenicians descendents - estoic merchants - and had a unique and cool culture. But the geographical presence, certainly, would make grow diferences among Phoenicia and its colonie - like happens in history -, the point is:
1- They live in africa, but they wouldn't be influencied by southern peoples. Probably would happen the opposite...
2- Carthage only would survive if don't fall, and this would change everything - christianism, commercial relationships, the romanic domination, germanic invasions and the islam...
3- One thing would certainly happen: They would participate in the colonization of the new world, and probably would take spain place...
4- Carthage wouldn't be religious, probably wouldn't be muslin, and will become christian but will not ntake this so seriously... (if cristianity blow in europe... because rome was the "vetor", and in this scenario there is no rome like we know...)
5- With the time Carthage would became a state ruled like vitorian England was... They will start to have their own units in middle ages, and would have units in a diferent style... European, but a lot of mediterranean view... Carthage employ mercenaries because didn't have population enough to fight against romans... It's only one city, and some colonies, far i know they never reach 300.000 people... And only the Region of Rome has more than this in the time of the second punic war... (the modern "lazio").
Punics were good soldiers and commanders, some of then were created for war(commanders), others for trade...
6- In second war they would be in no side... And probably would invade Italy...
7- It colonies in the new world wouldn't need to fight for independence, they will negociate to be "free"...
