Suggestion flowing forth from several ideas already presented in this thread: Global projects Certain existing and new projects are now built by a global production effort. This means that every civilization can sink production in it, and it is built when the accumulated production hits a threshold (the production cost). The main effect of these buildings/wonders is global, but the civilization which contributes the most gets a bonus in its capital. The Rights of Man. Requires Constitution +1 in every city of civilizations which use slaves +1 in every city +1 in every city +25% GPP Builders' bonus: +2 Great Statesman GPP Unhappy citizens in this city produce +1 The United Nations Requires Mass Media Starts global elections Gives a worldwide +1 relations boost between members Builders' bonus: Candidate in every election Foreign culture and heathen religions do not cause unhappiness The International Space Station Requires Satellites +10% +25% Spaceship production Builders' bonus +3 + 25% Spaceship production Human Genome project Requires Genetics +2 (Base Genetics boost gets nerfed) +5% Builders' bonus No in this city These projects could be easily coupled to the Humanitarian victory (invest x hammers in global projects, build at least one of them).
