General rules:
1. you need to expand extremely fast
2. you need to research Univeristy within 1 turn (300 beakers needed).
So if someone is slow then ~28 decent cities is enough (or less with GB for EIC).
This week i expand very slow, maybe i should make less of cities. But i have 60 beakers for Literacy at 200 BC, maybe 300 BC is possible, maybe i should research Literacy within 2 turns? But i'm not sure about 120 beakers for Democracy. Maybe i can expand 2-3 turns faster but i will have ~28 cities, majority 3-pop only, so GH is critical (and GS for Ind. or i need 3 turns for Ind).
But more cities = more gold and more beakers (you don't need +2000 gold for libraries, i needed 1 library for 160g). And big luck with GPs isn't critical.
