I'm trying to determine when to build wonders. I played a couple of games on king, built a number of wonders in each and all was fine. But I just tried my first game on emperor, and tried to build 3 or 4 wonders. Got over half way through each but someone always beat me to it. So, a couple of questions. You just loose all the lost production when someone beats you to a wonder, right? Also, is there any way to tell if a wonder is likely to be already in construction? Late game obviously if you are ahead on tech you are good to go, but early game I'm always behind. Are there certain wonders that AI's prefer? Do people just not build wonders on the higher difficulty levels? Cheers!
