You know, I am slightly dissapointed with mega changes some of the new crowd is doing. I am not taking names, but what happened with just one free Great Scientist, or a new, resource, or growth of forests, or just adding a few courthouses?
Wasn't big enough? Some people like instant gratification like action and explosions. That seems to be the case in the new DI's with big changes. The lesser changes you also need to appreciate the subtley of a story arc which some people don't do.
I don't mind big changes as long as they are done in the fog of war so that it's believable those changes has allways been apart of the world. My personal enjoyment comes from making the world seem like a living place with it's own history. See the ruins of a old nation surrounded by fallout, start in a ice-age and watch it melt away slowly etc.
