Civ I when I was a kid in the early 1990s. I loved it. Then: nothing (many games but nothing from the Civ series). In 2007 a friend of mine gave me his Civ IV disc so he would not be able to play it anymore. I made good use of it. I haven't played a single hour of V yet because I still haven't played enough of IV (though I took month-long breaks from playing every now and then)! Crazy when you think about it. I am hopeful for Civ VI, and would very much like it to be good. But ultimately there's not much we can talk about right now. As elitetroops stated some pages prior, all the cool stuff like Eureka moments, districts, the different "tech" trees and combining units could end up being groundbreaking, or just some pretty distraction. Here I'm speaking from the perspective of someone not interested in firing up a casual game every now and then but in getting better and better at the game while still experiencing different paths to victory. A big part of the game's quality will be how the AI is going to cope with all those options, especially with combat but also diplomacy, research priorities and city specialization.
