That used to be my strategy and it seldom worked. I would go right to Literature (after first getting Masonry so I could start the city that was going to get the Library out on the Pyramids as soon as possible. I skipped all the simple stuff (horseback riding, pottery, etc.--figured I'd get that in a rush when the Library got built). If you do build it, it works techwise-you're all caught up) but dedicating your best city to a wonder so early makes you militarily weak. Think of all the swordsmen you're foregoing. When you're weak, they know, they attack. Now I go right from bronze working to iron working, only build about five cities, put temples (so their areas will expand) and barracks in all of them and just build swordsmen and go after my nearest neighbor. It seems to work. I play Japanese, so I don't have to worry about revolutions and I sometimes luck into some wonders with my Great Leaders. Last game I didn't bother to build the Great Library but did manage to take it away (from the Zulus, no less). Alternate conquer with improvement building (Swordsmen conquer, build improvements a while (libraries, etc.), medieval conquer (of course I've got samurai), then build, cavalry conquer, build, then finally tank conquer). There is no downside to always being the strongest militarily. Strangely enough, I'm also number one in culture cause I always put temples and libraries in the cities I conquer. By the middle ages and shortly thereafter, I'm always first to the tech that builds a wonder (and usually have enough great leaders to do most of them). Of course, all of this is after a long (long, long) time trying to progress from warlord to regent. Don't know if it'll work when I try to move up to monarch.
