I'm quite tired of culture taking too much place in civ. For example: Borders should not only be expanded by culture, it should rather be expanded with diplomacy. You should not have to take a whole city if it is only one little square you want. I would like more politics in this game, more diplomacy and respect for military strength instead of culture deciding what resources you will have access to. There is much more, of course, but I find this most important. I really hope they change this.
