Like many, when I first started, I went through the phase of wonder addiction, trying to grab all that I could. I learnt that this was hampering my play, and went hard in the other direction - trying to build few if any wonders, and pouring those hammers and slaves into expansion and military instead. But I think I may have gone too far in that direction. Some wonders provide substantial benefits, in the right situation. GLH with an island empire is great, for example, as is GL, especially if you also have the Pyramids for Representation. So, my question to you all is: Which wonders are most worth their hammer and opportunity cost, under which circumstances? Coda to the main question - which wonders are worth building in almost any game, assuming doing so isn't going to hamper you too much in other areas, and which should only be considered under very specific circumstances? My own list would definitely feature: - GLH if significantly coastal - Pyramids if stone, industrious, or SE planned - GL if marble, pyramids, or philosophical I like the Mausoleum and the Taj also, though I'm less convinced they are worth the cost.
