I am one of those people who were seriously disappointed by Civ 5 on release, and when the first few patches didn't bring any fundamental changes, I never touched it again. Atm I feel a desire to play Civilization again, and wonder whether I should go with the tried and true Civ 4 or try Civ 5 again after a year of evolution. I am more of a builder than a warmonger. What really put me off with Civ5 was that city placement really didn't matter anymore because resource bonuses were so small, you could just plop down cities all over and not have any penalty for it. Buildings and wonders didn't have big enough effects for me. I missed rushing and found it rather very stupid that you could insta-buy at the start, but not rush later... Didn't like the random city-expansion either. And then there was the ultra-stupid AI. Have these things been changed? Especially the part about importance of resources as city-boosters. Putting my cities into optimal places and watching them prosper from it, snatching that one great spot from the AI and thus making my day and ruining his, that is the most fun in Civ for me. And the Civ5 I saw after release had none of that at all.
