Note: I don't claim this to be an appropriate solution for everyone and there are no doubt flaws that can be exploited. It's merely an attempt to make the game more enjoyable for myself and anyone else that might agree. 1. All resources/buildings reduced to +1 Happiness. 2. New city Unhappiness raised to +5 from +2. 3. Military Units produce scaling Unhappiness based on their strength/how high up the Tech Tree they are. 4. Citizens produce +1 Happiness. 5. Citizens don't produce Science. Science is limited to Buildings/Policies/Specialists. Explanation: With increased city Unhappiness and Happiness tied to population, each city will have to grow to at least size 5 to break even. Tying Happiness to citizen population will also create a sense of a recurring reward in the form of population growth - the growth of cities beyond ICS size to mega-city sizes of 20+ will become highly profitable as this will be your main source of Happiness. I've created a mod that employs these features plus others including specific government types and Taxation. Civilization NiGHTS on the mod hub. cheers.
