I think rushing wonders is in general not a great play, using GE for golden age is better. Compare the payback of the two and you'll understand. I consider only GM and GS as strong s. GLH and Mids are game changers under the right conditions, sure.I don't get a lot of GP early if I'm going for a culture run. My ideal strat (if possible) is to get Pyramids, then use an engineer to rush-build Sistine Chapel, especially if I don't have marble. I also like to rush wonders in general rather than get Golden Ages. I really like Great Lighthouse and Colossus because I frequently find myself claiming cities along the coast after pushing as far inwards as comfortable.
