Athens is a good choice. I mean their whole "democracy" thing was roughly 20 years long and only applied to male citizens. And trying to play nice withe the Persians really came back to haunt them.
Sparta was pretty sweet. I mean except the whole beat and torture slaves thing, but no one is perfect. But the first implantation of heavy infantry formations dominated. And stabbing dudes with spears appeals to me in a Freudian sorta' way.
Can't go wrong with Rome. Those motherfuckers were brutal, but damn if beating the rest of the region to dust didn't work. Not to get political, but we Americans could learn a thing or two from them; if you have military bases in other countries to "protect" them, might as well tax them too. Harsh, yes, but history shows us the biggest fucker wins. Might as well go whole hog.
Golden Age European Islam wouldn't have been so bad. Again it was like 20 years long and benefited men more than women, but those were a decent 20 years considering the time. But then again, it was basically a second attempt to recreate Rome/Greece/Egypt with a few bells and whistles. Still, considering all of history, you could do worse.
Hmmm...Victorian England/New World would have been fun in a Lovecraftian-Sherlock sorta' way. But lots of poop related deaths and bad teeth. Can't imagine tongue kissing a woman who has never brushed. *Shudder*
