@ jacyp @Anthropoid, as far as I know, Sid and the guys sold the franchise but kept some right via working for Firaxis. Sid basically took a bunch of cash out of it, and decided he wanted to try out some other projects along the way. He wasn't as active in civ5 dev, if you look at some interviews. It seems to me like he took his little facebook team and went into a little room to play around with his idea. This is after Civ Rev failed. So imho, Sid just doesn't want to design games like he used to, or he's grown old and out of touch. When you're older you generally prefer to play simpler games. It wouldn't surprise me if he was the main force behind simplifying Civ5.
