Questions on Sauromatae gameplay

[I of the Storm]

Well, I have never really played a nomad faction before. I now started a sauromatae campaign, 1.2, RTW.exe, m/m and played maybe 10 turns yesterday. Looks fun so far, I might stick to this for a while.

I collected my troops into one army, defeated 2 smaller rebel stacks and took Tanais. Right now, I laid siege to Olbia and hope they will sally, as currently this uber-stack that you can put together with your starting army is a real overkill firepower-wise. Envelop, create crossfire killing zone and wait for enemy to finish dying. I intend to take the Crimea then, hopefully reducing my troops which I suspect I will be needing rather sooner than later against Hayasdan, once they have taken Kolchis(?). Currently I'm already 9K in debt, but I'm not too concerned about this. I hope the three greek settlements there will get me some money.

Anyway, I need some advice by you more experienced nomad players.

1. What about governments. It seems that I can build nomadism only in a couple of steppe regions. In many other regions I cannot build nomadism. There I have to build what? Pastoralism? Client Kingdom? I'm lost here.

2. Military. The main armies will most probably be horse archers of various quality and heaviness for most of the game. But what about local troops, especially in those greek areas on the Crimea? Do I need allied kingdom or pastoralism to access these? In the RV I saw the lovely bosphoran archers. What do I need to build, and where to get them?

3. Speaking of military: Do the Sauromatae get any reforms similar to Pahlava or Saka and if so, what new kinds of military do they get?

4. General strategy: Is the above outlined strategy a feasible one for early game? Should I aim to take out some neighbours early? Blitz Getai or Hai? Is the east baltic area worth the effort at all? Mid- to longterm I'm thinking of aiming for Greece, get rich and then go Hun on everybody else.

5. Language. I can't make out what kind of language the EB team used in the unit descriptions for Sauromatae. Any scientific insight into this subject would be very appreciated. Also, on the battlemap, there seems to be a semi-completed voicemod for them?

Thank you.
