Only the ones started by the great person. First one is 7 turns, second is 6, and so on. Also it can't drop below 3.
Questions :
- From the tech tree, how can you tell if a building is a wonder or just normal?
- I had the tech for Musket, but I was not able to upgrade my archer to it. I upgraded it to crossbowman, but even then can't upgrade to Musket or anything else...
I guess you can't see the difference, other than that the wonder is typically the name of a real world construction and the buildings are more generic.
Crossbowmen can be upgraded to Riflemen a little later, though all their ranged promotions lose their use. It's a feature
hot seat game isnt in civ5?
I hear it'll be available in a future patch.
