One of the most important rules for at least slightly advanced civ players is to sell all your unused resources. In early game, an additional 7gpt from a single luxury surplus or 6gpt from 5 units of a strategic resource is always worth it (numbers for epic-speed games). Even slightly lower values are acceptable. AI has enough happiness to support itself anyway so you are not really helping them and when it comes to strategic resources, even if they go to war against you, they will get huge penalty for the lack of proper resources to maintain their troops. A win-win situation.
There is one exception, however. If AI does not have any coal, there is no reason to let them pick an ideology before modern era. I don't know about uranium because I have yet to play a game in which AI builds at least a single nuke. Especially since BNW, my games end earlier either with diplomacy or culture.
I was thinking, though. If I'm able to amass huge amounts of happiness, and I sometimes do, I don't really care for resources as happiness boosters. Their main purpose is to trigger faster growth in my cities. AIs, who always have tons of happiness no matter what, have the same use of luxuries. Is it really worth selling them luxuries for meager 7gpt each if your total gpt is around 150 or more? In my recent games I tend to trade everything off to allied civs but I withhold my luxuries from civilizations that cannot be trusted or are my general rivals.
What is your approach?
