Do airports have any bearing on trade in the game? As I understood from the manual/civilopedia, the only thing they do is allow airlifts. Well, that DOES help for quickly moving freights about, I suppose....
Actually from a reality perspective it WOULD make sense that airports enhance commerce, I just didn't think they did in the game....
Oh, my five?
--Cathedrals (I often get beaten to Mike's, since I often downplay religious research in favor of industrial-leading research and build colloseums--might try the religious tack more sometime though, especially when I venture beyond my current prince level)
--Colloseums (like I said above, available early and INCREASE effect later, not decrease like Cathedrals do)
--Factories (and Manufacturing Plants built later)
--SDI Defense (my goal is to get as many of these up before anyone decides to build the Manhattan Project--the only time I'll FINISH Manhattan is if someone else starts it, to get the points for the wonder--that or right before my spaceship lands. I HATE nukes, and the inevitable global warming that follows their prolific use....)
--Airports (Airlifts, baby! Especially to those new remote islands I've just started settling)
I've been reading some of these posts about the trade link with science--never understood it much, knew they were related in the game but not how exactly. But these posts have given me some insight--seems more key than the libraries and universities I tend to build, although they still can't hurt either. I build markets, banks, exchanges and freeways as a matter of course in big cities too, and I guess that's what's helped me most in the tech dept. and I didn't even know it! Starlifter's strategies with freights, now that's something to try.... I guess I get lazy a lot and don't build a lot of caravans other than for wonders (i.e. going a short distance) or if I need a quick shot of cash and have uranium lying around.... But with what he said about freights, I guess it's well worth all that clicking long paths around the world (it can get tedious though with a sh*tload of cities spread all over the place).
Thanks, you've all given me some new insights. Although I bet no matter HOW fast you go in tech (right now I'm usually ahead but barely most of the game), the AI will find a way to steal it and share it with everybody, no matter how many spies you plant in your border towns.... Especially space flight and SS techs....
