Part of my ongoing education with CIV. So the ability to enter Ocean is tied to the unit - Galleys and Workboats can't (unless cultural radius allows it) and the other naval units can. So Optics, which provides Caravel, allows Ocean travel by permiting Caravels.
So if we build Colossus, Astronomy will cancel it out, so it may be worthwhile to research other useful Techs while we explore with Caravels to keep the Colossus benefit. Getting a 2nd GS can help us to dictate the timing for this. If we research Optics after Machinery, the 2nd GS would give us Astronomy for Free. (So Optics next sound good.)
Other Techs that lead us to Communism is the Theology - Paper - Printing Press route. Printing Press is required for Scientific Method (after Astronomy), which leads to Communism.
Communism requires Liberalism. From Paper, Education then Liberalism. Liberalism grants a Free Tech, which could be Communism.
If we can lead Gandhi down this path, that would be great! Machinery should gain us a Couple of Gandhi's Techs, and at each new Tech we can do more trading. We look to be on track to make contacts soon (after Machinery and Optics) - very good progress, and the Commerce game is coming under control.
PaulK - you're UP!
