why is it when i rush my first library it costs 80 (double the production needed) but when i go to rush my second library it cost 120 (triple production needed). does it increase with each building you rush? is there a cap?
you were probably in a diffrent era
no i normally try to do it within a few turns of each other
I.E. i rush a library in my capitol in 3000 bc
try to rush library in my science city 2500 bc
and by that time im still only researching writing or code of laws (my 3rd and 4th techs)
just read in another thread that apparently getting technology makes it more expensive to rush units? is this true? and does it hold true for buildings as well?
You must be moving to the medieval era (4 techs) only eras increase the gold cost of production hammers
