I'm at around 1200 ad right now and have Hanging Gardens, Great Library, Leo's Workshop, Cop's Observatory, KR's Crusade, and I'm praying I'm not beat to Sun Tzu's. I was trounced soundly on the race to Statue of Liberty, which hurts, and I've been in perpetual war with the English since I met them.
What drives me crazy, however, is that the English got Writing as I was researching Gunpowder, and I slowed my research so I could get the Workshop first, fearing a swarm of diplomats the moment I got it. I'm #1 in research and the turn after I build the Workshop I get Gunpowder... from the Great Library! This is going to be a brutal, bloody game if I keep playing it military.
