Steve2000 said:When a building goes obsolete (such as scientific method obsoletes monasteries) What does that really mean? Can't build it anymore? (probably) What happens to the ones that are already built?
In the case of monasteries, I believe that you can't build them any more, and you no longer get the 10% bonus to research. But they still allow you to build missionaries, if you have them.
Probably, the exact effects of obsolescence for each building type need to be determined on a case-by-case basis.
