question about science cost

I wanted to know which factors form the cost of technology advancement but was unable to find this information on official manual.
How much does map size affects it? Does number of cities you found somehow affects it (like with cost of adopting cultural policies)?

 

I think only game pace affects it... not sure though...

 

beaker costs for technologies are basically set. they're slightly reduced for each civ you've met that knows a specific tech. founding more cities (getting more beakers) will speed up technology gains.

also they are scaled to game speed, and are slightly reduced on the lowest three difficulties.

 

You get a slight discount for every Civ you have met that has that specific tech. I am sure that someone somewhere here has the complete set of rules for this.

 

maybe i made something wrong trying to get science win before 1000 A.D. placing a lot of cities with univercity on huge map but I was unable to achieve this through few tries. It took just a slightly less time comparing to the cultural play with less cities.

 

that's not possible unless you rig the settings, eg play on settler difficulty or marathon speed.

 

vexing, that's not the ultimate goal (though there were ways to make something like that in previous civs)... I just wanted to say that difference between playing with 3 almost perfectly build cities and 12-14 cities with early constructed scientific buildings is not so big. it could be even random difference... so that's why I started the topic.

 

Yes, Firaxis tried really hard to balance research between large and small empires. After 4 patches they mostly succeeded.
