Hey there Bill
Looks like your havin wonder problems there.
First things first there is no reliable way to rush wonders
other then the tactic to get leaders and burn those as Bcask
described. Leaders are things you should value and horde
if you get one when you are building a non consequential
wonder save it for something more important during ancient
times like the Great library or the Pyramids.
A couple of tips always build it in the city which has the highest
population and the highest shield output this will usually be your
capital city depending on what starting terrain you get. the ideal
being at least 2- 3 hills and at most 1 mountain mountains are great for commerce and shields but suck at food you need to keep that population growing. which is why i tend to build two
settlers at most with my capital city then leave it to the others to
go grab some iron or horses if I can find them.
Once you have 3 cities this is where the fun begins road all your stuff and mine the living hell out of everything you can which doesn't take away food from your population. You can always change the mine to irrigation later if need be. I have never had to. Chagne your capitol city which should be about pop 5 or 6 and just build your first wonder more often then not you will win. As I said in an earlier post you have to figure out which wonders you want and just hit the ground running to them ASAP!! Remember found your first cities with this goal in mind. Don't forget that some of the wonders like the colosuss and the Great light house have to be built in a city with a coast square in it.
what difficulty level are you playing at by the way it gets much harder after the middle difficulty because the computer almost mimics your research list. So you have to get your goal in mind and not be distracted unless you now some bastard declares war then its on. Hope this helps alittle
