Well.. I must say it was my dream at one point as well. I only realized how horrible my dream was Sirion expanded to Oligarch.
I think there are many players who want to build an empire only to realize later that they've been playing the game wrong
Fixed it!
And yeah, I've tried it before as well, but always seemed to fail (was attempting to build a theocracy empire with Sartania for instance). Tbh I wouldn't try it in that way, although I do have some other ideas for 'world domination' type of play that allows for a lot of fun and will ultimately lead to my own destruction no doubt
