Good suggestions. Some additions:
Saba:
bag Carna too ASAP, for three reasons:
- It is very close to your capital Maryab, and thus a very tempting target. Also a rich province.
- Your best nearby mining site (basic mines provide 1200 mnai/turn, upgraded ones 3000)!
- The Ka'ba. It provides additional trade income and a happiness bonus (plus, if you're a Muslim player, it is probably some kind of a status symbol).
Potential drawbacks:
- You will be closer to the two big evil guys north of you. Not an immediate concern though, since it does not border their initial territories and anyway, it takes decades for them to reach your remote provinces.
- There is a somewhat aggressive rebel army nearby.
Sauromatae:
Gelonus is seriously worth considering even right at the start. It has your regional barracks already built and you can immediately recruit Vojinos from there, who are a) cheap, b) strong vs cavalry and c) frighten infantry. This can be a great help for the next few raids, especially those against walled cities.
Only drawback: it is not a particularly rich province.
