Considering Ptolomai campaign at some point

[Arjos]

Ptolemaioi have quite a secured base, once you control the whole north-east Africa...
There are scripted invasions at Kyrene by the Karthadastim and the Seleukidai will knock on your door constantly, with the Sabyn joining the party later on...
In overall they are a very rich faction with decent units, but their gov expansion is quite limited compared to other Epigonoi...
But they all share culture, so you could let your enemies build up their infrastructures while you conquer in Africa (that's what I did)...

In the end, like all factions, they have their own flavour and make an interesting game...
It's a dealer's choice though, if you don't like them, you can always change :)
