I tried an Assyria run (forming Assyria as Adiabene, a tributary under Seleucid) but despite murdering two kings and placing my 0 year old grandson on the throne, they suffered no ills. Right next door Phyrigia remained intact with 50k manpower and 2500 gold. I’ll have to try that again. I really want to try some nation with Persian tradition (I love horse archers) but can’t seem to find one I like.
As for tribes, three recommendations (which may or may not have achievements associated with them. Alas I like my mods so no achievements for me.)
- Dacia Region
Lots of local resources - iron, horses, precious metals, livestock, trade for horse archers and with access to a farmland gem province (one of only three gems in all Europe, the other two being on uncolonized lands.) Form Dacia, free CB’s on the entire region. You’ll have to colonize - which I like doing, but many do not.
You get this decision:
Spoiler: You end up with five iron in the capital province.
- Lingonia. Unlike most tribal realms, you have a lot of slaves (33.) It’s very rich, can support a large army and navy (even with the penalty to tribal army support.) My intention was to ally with the Etruscans to fight Rome. Alas that failed and I’ll have to try again.
