@isau To me, you should be buying T3 buildings with gold not hard building them with hammers. Hammers are for ancient empires trying get up their first campus. Gold is for modern advanced empires that are now using PPPs to get important infrastructure up to impress the voters. Bang, Research Lab. Bang, Stock Exchange. So, I don’t really like the idea of production cards for T3s. It’s interesting T3s don’t benefit from City States. I’d never really thought about it before. That’s maybe another reason there should be more and stronger policy cards that leverage them. I could also see them having bonus effects, but I’ve never come with any ideas I like. Or maybe there should be a World Congress session where you force the AI to build T3 buildings while you project and chop your way to Alpha Centurai...?
