OK as a disclaimer: I love EB and would have had probably months of more productive activity if it weren't for this immense mod.

BUT why do barbarian (for wont of a better word) factions not have the chance to advance beyond a tribal coalition even when they get rich and powerful?

For example in my Getai campaign I have a decent-sized empire, a strong economy and I am the 2nd greatest power points-wise. I have conquered all of Greece and inhabited their huge cites. So why do the Getic builders still not understand that paved roads would be awesome?

Surely in history if a small tribe started an empire (like the Romans) and encountered the more advanced technology of other nations, provided they had the economy to support it, they would attempt to employ this new technology.

I understand that for some factions it would seem pointless (why would the nomadic Saka want huge walled cities and paved roads when they lived on the endless plains of Asia?) but surely if those factions who were underdeveloped in 272BC started to make it big, they would upgrade their technology.

To be fair it's mostly paved roads that bug me because I can just see no reason not to build them if it was possible. But I guess stuff like seige weapons would be awesome too.

Does anyone agree with me? Feel free to debate it and if you can satisfy my queries then everyone's a winner because I will be even more happy with my Getic Empire and my new AAR will be better.
