Well, we are currently researching Espionage and will soon have lots of spies.
So, what should we do after that? In the previous long-term planning poll, citizens chose Corporation -> Refining. So, should we follow that? And what should we plan for afterwards? Once again, our possible choices:
Magnetism -> Electricity
This will give us destroyers (4.4.6) with Electricity, but as I said in the last several polls,
I suggest we hold off on Magnetism as long as possible so that our ironclads can get the greatest benefits possible from the Great lighthouse, which magnetism would obsolete.
Corporation -> Refining -> Combustion -> Theory of Gravity -> Flight
Corporation will upgrade our caravans to Freight and allow Capitalization (shields to wealth). Refining gives Power Plants (benefits to factories). Combustion gives Submarines (10.2.3) and, along with Theory of Gravity, is a prerequisite for Flight.
Theory of Gravity -> (Combustion) -> Flight
ToG gives Newton's college, and is a prereq for Flight (with combustion). Atomic Theory is a prereq for Fission, but we'll need Mass Production first.
Corporation -> Genetic Engineering
Gives Cure for Cancer (extra happy person in each city)
Guerilla Warfare
Gives Partisans (4.4.1, all terrain as roads)
Theology
Allows for Bach's
Sanitation
Gives Sewers (cities can grow past size 12)
Fundamentalism
Gives fanatics (4.4.1) but since we have the statue of Liberty we can change gov'ts at any time.
