Oh, come on. Most of the Civ info has been posited from the Civ 3 info site.
Most of the leg-work for the Civ 4 site is design and flash. Yeah, I can see that taking a long time.
But the content should be there. Unless the absent leaderheads aren't finished (Napoleon, Liz, Bismarck, et cetera), all civ info and leaderhead info should be present. Really. 18 civs, and what? 26 leaders? And then you copy-paste (with the exception of Mali) the blurbs from "Civ of the Week" in Civ III. That is a DAY's work of web design, if that.
The longer process is getting images to bulk the design and layout of the site. The site is beautiful, and the music is gorgeous. But I think what people REALLY expect from the Civ4 official site is the list of civs, teaser images of civ leaders. Come on. For the average consumer, in-game screenshots are fairly boring. They blend together, for the most part.
Civ4.com should pimp the music, wonder screens, some in-game shots, and especially the CAST OF CIVS. Those are the neccessities of what is -- esentially -- an official advert for the game. The rest is all bonus.
But it still is reeeally pretty to look at.
