How do you do that? I don't plan on making them easy to recruit, something like five or six turns. I kind of feel that the thirty-turn recruitment is a bit extreme. Sparta had a small population of Homioi (Spelling? My apologies, I'm a history major but not that great on the Greek language...), but it was large enough that the thirty turns is kind of...urgh.
Also, if this is done, is it save game compatible? Or will I need to start a new campaign?
