I think a nice touch would be to have various country flags as scenery objects so that if a certain ride was recreated that country's flag could be placed near it. For instance if I recreated the Cyclone roller coaster from Coney Island New York, I could place the American flag near it. If a ride from efteling park was made, the flag from the Netherlands could be placed near it. This would not only be theming, but would show where the ride came from.
