Here's a glorious, picturesque moment midway through my latest Carthage campaign. The Allied Camel Corps of Carthage and Nasamones meet and begin a joint siege of a long-held Desertic rebel city! This was quite cathartic after we each spent years playing tireless whack-a-mole with the rebels across the Libyan desert.

A proud (if ultimately meaningless due to the frequency of rebellion in this playthrough) moment in a very strange timeline. After uniting Italy, Rome focused literally all their efforts expanding directly East as far as possible into the Balkans, Greece, and modern-day Austria and Czech Republic, and Thrace. However, they fucked up bad in the first 40 turns or so: the Semones (or whatever their name is) somehow managed to conquer Rome and hold it for an entire turn. Ever since then, despite re-capturing their titular city, the capital of Rome has been Neapolis.... So, I guess they are technically the Neapolitan Empire now?

So anyways, the glorious Neapolitan Empire has devolved into some crazy six-way civil war that I have no intention of entangling myself in.
Also, hilariously enough, Parisii conquered most of Britain and wiped out all the indigenous tribes (except the Picts, who just sort of collapsed and vanished into obscurity). Didn't see that one coming.
EDIT: Also, as a random side-note, I noticed that rebel factions can fight each other (i.e. Semitic Rebel regions and armies will be allied with each other, but hostile towards Desertic Rebel regions and armies). What an awesome feature. Goddamn I love this game.
