I was thinking about the Carthaginians the other day and I had a couple of thoughts.

They would not call themselves Quarthadastim. I could be mistaken, but as Quarhadast (The true name of Carthage) meant 'new city' in Phoenician then Quarthadastim would be something like 'People of the new city' I don't know for sure, but I would like to know why EB wants them to call themselves that.

Phoenician colonies. It was mentioned on another thread that it should be possible for Carthaginians to recruit at least their militia citizen phalanx from any city with a Phoenician colony. After some research I discovered that this was, pretty much, true. The Phoenicians would colonize places and then the colonists, still being Carthaginian citizens, would, in times of need, form citizen armies much like those that fought invaders in North africa. Of course there was supposedly a difference between colonial citizens and homeland citizens though I couldn't find anywhere that said what the difference was. I suspect this difference would have had something to do with local influence. The ability to recruit these citizens after building a colony would help in areas where Carthage can't build any troops, like in Latium for example. It's really annoying in the campaign to capture Rome and then be unable to recruit a garrison.

Carthaginian naval reforms: The Carthaginians, at the outset of the Punic war had a large number of ships partially beause they contained very small complements of armed men(marines). Partway through the Punic war the Carthaginians began outfitting their fleet with more marines and more specifically the best pick of their most skilled mercenaries. In game this would be a normal reform with the Punic fleets starting out with fewer men than they have now and then after the reform their ship complement is brought up to what it is now.

Carthaginian land forces reforms: In addition to the reforms you already have. After Hannibal had fought several battles with the Romans his men began to use Roman equipment they had captured from the defeated enemy. They took armour and weapons from the Romans but not shields so that they would not be mistaken for the enemy. It would be cool to see Iberians, Liby-phoenicians, africans and Libyans armed with Roman weapons and armour.

Libyans: It is mentioned in the accounts of the invasion of North Africa by Agathocles of Syraceuse that he convinced the Libyans to join him and that these included Libyan chariots. It is also mentioned that the Libyans were charioteers in the same way as the Balearic Islanders were slingers, it was a natural passed on speciality of the locals. Agathocles' invasion of North Africa took place approximately thirty years before the game of EB starts. There would most likely still be local Libyan charioteers and also likely mercenaries as well. The Carthaginians didn't employ them in the Punic wars, but they were still there if a brilliant Carthaginian general had known how to use them, or if an invader had been able to rouse them against their Punic masters. Also, Libyan cavalry is suggested in Polybius' account of the first punic war and the Mercenaries war. In the Punic war there is an account were he mentions the cavalry of the Carthaginians going ahead of the army and then he says that the Libyans fell back to the main army, drawing the enemy in. In the Libyan/mercenaries war, it is mentioned that the rebels received infantry and cavalry from the Libyan cities that joined them.

Xanthippus: I must protest to the way Xanthippus was portrayed inEB 0.74. He didn't arrive in North Africa until at least eighteen years into the first Punic war, and that started ten years after the start of EB. That's 56 turns! Not that the Carthaginians couldn't have hired him sooner, but he certainely wouldn't be in Africa at te start of the game. Now I understand the limitations that CA has put on EB, so if none of suggestions are plausible than the EB team has done the best they can and I approve.
Suggestion #1: Xanthippus starts on a ship with some greek mercenaries (as it was said that he came over with Greek mercenaries hired by Carthage) on his way to North Africa. This one is probably not possible but if it is then it is a good option.
Suggestion #2: Xanthippus starts as a Carthaginian general in Greece with a transport awaiting him.
Suggestion #3: The most historically accurate, though not neccesarily possible. Xanthippus starts as an eleutheroi general in Greece with traits that make him easy to bribe and a Carthaginian diplomat right nearby.

Skiffs: During the account of one of the many times in the first Punic war that Carthage rebuilt her fleet it says that they outfitted triremes, quinqueremes, and the heaviest of their skiffs. I don't know exactly what a skiff is, but its just a thought for making the Carthaginian fleet more diverse.
