I think this would be way, way too cheesy if it were to be implemented with actual real life natural wonders. I mean, it's okay to have your Eiffel Tower in Beijing or something, because the whole point of the game is to recreate history, or resimulate it, or whatever. But having a Great Barrier Reef next to Russia or the Himalayas in Holland would be a step too far. It's not something in history that you could change.
I'd be for this to a limited extent, supposing the names where made more generic, though (like the corporation names are generic). Just have, like, 'the Alps' and 'Reef' or something.
