The Great Wall = GW The Great Lighthouse = GLH The Great Library = GL Lately I have noticed that my games have evolved into 2 main types, in which I get 2 of the 3 "Greats", and rarely chase more before Paper. In most games, I generally go for the Aesthetics-early GLibrary-generated GSs for Lib" plan at some point after the break-out phase. Its a very effective path that allows reasonable trading and a strong Wonder that is usually not high-priority for the AIs. The choice of the other Wonder depends on the lay of the land. If its a single landmass or big continent thing, where I have met over half my opponents before Writing, I go for the Great Wall. If its looking like there's a lot of coastal real estate with plenty of "Chicken of the Sea" resources available, I focus my effort on the GLH. I think both are solid game-changing wonders at my level (Emp). The GW can pop an early Spy, and when settled, usually means you will not have a need to pay much attention to the Espionage screen and will eventually get to see the Current Research of every AI. That makes trades and racing to techs a breeze. I love selling off one-turn of a tech to an AI for a big pile of gold, heh, its almost an exploit if you have every AIs recearch info. Its especially strong when you vassal a techer early, and can tell him what to research while you get the "first to" bonuses. The GLH needs no introduction. If there are reasonable, well fed locations for you to put 80%+ of your Empire on a coast, its a game-breaker, even at Immortal. In fact, all of my Immortal victories (not many, to be sure) have come on maps the AI sucks at, watery GLH type non-isolated isolation sprawling empire maps. Even at Emperor, I struggle to build cities fast enough to crash my economy once the GLH is down, especially if there are other-landmass spots. An other-landmass city, with the GLH, is break-even maint ~ 50% slider the turn its built. If your EXP, you can whip that Granary and Harbor ASAP and watch the vertical growth/TR profits zoom. Send Work Boats out with the galleys carrying Settlers, and jump-start these crazy cities. Its the "style" of game I have the most fun playing, especially now that I have discovered Large maps with Low sea level. Lots of coast in those. I used to be quite a horrific Wonder-hog. Climbing the difficulty ladder has toned me down quite a bit (until late-game that is, then I try to get every Elect-Radio-Comminism Wonder I can). Still, these three "Great" Wonders are very strong to be sure.
