I'm exhausted.
Yes it is one tech per turn, faster than last game. You can try my "Imba II" savefile, the first turn after switch. Strategy:
1. Start GA immediately.
2. Switch to guilds. It costs 2 turns for any further civic change, for you have a large empire. Research drama by overflow in anarchy.
3. Wipe out Greeks (Shanghai, unguarded) immediately, I had a knight standing by Beijing.
4. 1 tech per turn, bulb tech when you get great people, it saves you 1 turn.
5. Seljuks? No problem. You'll face Mongols, Mughals and Turkey flips later, refuse all, destroy them by riflemen...(you can surely get rifling before 1190)
6. Build a spy and steal philosophy from Moors if they don't trade. (I didn't do this so I cost one more turn)
7. Build the Verseilles before your first GA runs out. I discovered printing press before complete, so I switch to secularism right away. Build catholic missionary in case of the city loses catholicism.
8. Beeline steel and steam power, later era brings you less city number maintainence.
9. Liberalism for whatever. That brings you an UHV, and 3 cathedrals are pieces of cake.
10. Play at will...... in this game I would launch spaceship in 1460, I think I can push it further, like 1450. How about no more revolution before Cristo Redentor?
