When AND's DLL and XML tags were updated with code taken from C2C, one of the tags that was introduced was <GlobalBuildingExtraCommerces>. This tag would allow a building (most likely a Wonder, but not necessarily) give a global bonus of one or more commerces gold:, , , ) to all buildings of a given type, in the same way that Modern Art increases the culture of all Theatres on researching the tech. I haven't yet used this tag, but I think there are some Wonders that would really benefit from this to give them special abilities that aren't shared by other Wonders, replacing some of their existing abilities.
Hanseatic League: Replace the connectedness commerce bonuses with +1 gold from all Market and all Harbor/Port/Seaport. HL goes obsolete before International Port comes on the scene, so it doesn't need to be included.
Isaac Newton's College: Remove the innate +2 raw science and cut the science percentage bonus from 50% to 25%. Add +2 science from all University, Laboratory, and Research Laboratory. I think World Wonders should try to have a civilization-wide effect, and Newton currently doesn't have any.
Bolshoi: Replace the free Theatre in every city with +2 culture from all Theatre and Opera House. Free Theatres don't mean a lot because they are available in the Classical Era and Bolshoi is Industrial Era. This would make Bolshoi more interesting.
Federal Reserve: Replace the free Bank in every city with +2 gold from all Bank. The free Bank was kind of a stop-gap because I couldn't think of anything better. I think this will make a much bigger impression.
If there's any other Wonders (national or world) you think could benefit from these kinds of bonuses, let me know. I want to keep this off regular buildings because it will stack, and I don't think that is a good thing.
