The best way to enjoy Civ is to play it in every way possible.
I enjoy playing Civilizations 3, but have no desire or intention to play in every way possible. Many of the civilizations do not interest me in the least, the Aztecs least of all, nor am I interested in playing every government type, particularly communism or fascism, both of which are idealized in the game.
As for the list of so-called "addictions", so what. I like huge archipelago or continent maps, with limited numbers of AI players, so that I can expand in peace and quiet, without the annoyance of the AI. Why is that bad? I like Seafaring civilizations, which work very nicely on water maps. That automatically makes me a poor player? I have never played Republic, and probably will not. I normally do not even research it. Does that mean I am the Abomination of Desolation? I modify the maps, buildings, Wonders, resource yields, terrain yields, improvement times, etc. since I finally have a Windows box for game editing, and stack things my way in the game. Horrible and hideous of me, isn't that? But I have fun playing the game, which is MY BOTTOM LINE.
You want to tell me how you play, that is fine. Do not tell me how I should play.
