I'm really disappointed in Civ 4; it's just no more fun. Yes, they fixed some things that were annoying in the previous game, but they didn't make it better, in fact they screwed it up! The interface is just such a mess! It's like the dashboard on a Jaguar; you can’t find anything on it, where the Civ3 interface was nice and clean - fewer buttons which did the exact same work. The Graphics are nice but it’s kind of hard to distinguish a warrior from an archer and hard to see if you have any units in a city and how many of them are in it. Another thing is that there just isn’t enough time! The 650 turns in the normal setting fly by very fast - 6h55min to be exact, that’s how long it took me to finish my first game. Where in civ3 you would play the same game for weeks. Before it took so long for 2 reasons:
#1 the worlds we bigger in civ 3 (huge in civ4 is like standard or maybe large in civ3)
#2 unbearable loading times in civ3 which we "fixed" in civ4 (probably because the worlds are smaller)

The world builder - Where is it? Oh no it’s not in the start menu, nor in the game's main menu, no no no. You have to start a new game and then you can enter the world builder to edit the game that you just started... What the F*ck!?

I have so much more to say, ill maybe do it later on. To tell the truth I just hope they release a new expansion that would fix this game because this is just a huge waste of money, it would maybe appeal for young players (8-14 years old) on people who have never played previous civ games or rts'.
