An Academy from a pure culture calculation is a mistake. But I decided that it was more important to win the race to Liberalism
???? I imagine you mean from a pure
science calculation.
And thats the point, if an Academy gives you less than 1000 beakers in the way to Liberalism, you will be more likely to win the race to Liberalism if you lightbulb half of Education.
I think P.Press pays off. It only takes about 6 turns to research.
Now, I think you are wrong here. 6 turns in Quick equals 27 turns in Marathon, it is a looooong time.
Assuming that:
- After civics changes your capital will generate 500cpt at 100%culture.
- Before civic changes your capital generates 100cpt at 0% culture.
- Printing Press takes 6 turns to research at 100% science.
- There are 10 cottages (towns or almost towns) in the capital.
- Culture multiplier in the capital is 4.
- It took 36 turns since you went 100% culture till you won.
Then
- The effect on the 2nd and 3rd cities is negligible. Researching Print loses 6 turns of culture generation and brings no benefit (no cottages there), but it doesnt matter since their cpt is around 0 and both cities go beyond the limit thanks to culture bombing.
- If you dont research Print, you run always 500cpt in the capital and you win in 40 turns.
- If you do research Print, you run 100cpt in the capital for 6 turns and then you run 540cpt for 36 turns for the same result.
So according to my calculation you are 2 turns worst if you research Printing Press. Do the assumed numbers resemble reality?
The conclusion seems to be quite reliable when numbers change. Only if capital output at 100% culture is lower than 400cpt researching Print becomes beneficial.
Of course this is only theory. There are factors not taken into account, like the probability to trade Print for Banking or Economy thus further improving your economy.
