A world’s fair is a gathering of people from many parts of the world, at which they demonstrate their products and their arts, and promote their homelands.
In case you didn't know, that's what a world's fair is.
Pavilions would just be small building INSIDE of the big building in the HOST town.
The big building would only be built ONCE THE TOWN IS NOMINATED. Only the HOST town will build it.
We may run events, they have not been decided yet.
Small towns are welcomed to build pavillions inside the host town's building but it is unlikely for them to be nominated to host for a while.
I hope that clears up a few things.@Photoave12
