First of all, I would like to show you a quote from "Candelarius Extended Realism Mod" readme in the Docs folder in the ExRM file.
"I decided to add the Kingdom of Galatia for practical reasons...the Seleucids need another "speed bump" faction..."
Well, here is my experience with Galatia; Playing as Rome on H/M. I'm not complaining by any means; I love the challenge. Pay close attention to the minimap on the bottom left of this picture to see the size of this "speed bump" empire.
CAUTION LARGE PHOTO...Sorry didn't resize it
Some Armies and Overall Ranking(Top 5)
Dacia is an Alli, so Maronia is the only place our two empires meet, and there is no way around the town, and my army, except through Dacian territory. Its pretty brutal, they send wave after wave of full stacks of infantry, which I mow down with my horses and archers.
