Well the purpose of this thread was that I was going to kick my wonder addiction but I wanted input from people.
It was obvious that what I suggested initially wasn't going to work. It would've improved my game in some areas but made it worse in others by building NO wonders.
Case in point, if you're going for space race victory you have to get the Space elevator. Or The Sistine Chapel for cultural.
I've identified 3-4 wonders for the entire game for my favourite leaders and I'm going to try a strategy where when I play them, I only build those wonders. For example, Pyramids, Parthenon and Sistine Chapel (if going for culture victory) for Pericles. BTW, I ended up rushing Parthenon with my second engineer. A nice pair of wonders to have without having to spend a single hammer on wonders.
So I'll see how I go with that.
But thanks for the suggestions.
I don't think that planning to get a certain wonders every time with a leader is usually a good idea. You need to take into account your situation and resources. Sometimes an early rush it a much better use of hammers than an early wonder say if you are constricted and can't expand due to neighbors while other times you may have plenty of room to peacefully expand and can spend the hammers on a wonder.
