It's not really economy, but I mean tech-wise, how do you advance? with philosophical, there's gonna be more GP (most likely great scientists) and you can simply let them join the city or bulb-teching, either way, your beaker will never be short. with financial, it's also a good idea to cottage anywhere near the river since you'd start with 3 gold! but what if you are someone like Justin or Boudica? how do you keep up with the tech with traits like 'aggressive', 'charismatic'? Bonus question: how many cities do you settle down normally?
