Aberdeen, Scotland would be good for a water gym due to its two rivers, impressive harbours, beaches and cliffs and connections to the fishing and oil buisnesses in it's history. Plus the Torry Battery would make a good spooky area. Or the city could be a rock-type area due to it's status as the Granite city. Plus it's important to Europe: it's Europe's Oil Capital.
I hope we get music to suit with the regions, liek this:
Scottish areas with country themes (Cities are pretty High-Tech in Scotland nowadays, so maybe some Techno/Rock vibe?) and slight Bagpipe?
French areas with acordians and vintage music
Spanish areas with Lentimas-like music
English areas with classical posh music, while London-like cities would have punk-ish music.
Would be cool, right?
