Well, we've all played through Poland a few times at least!
What are some locations you have wanted to set a game in apart from Poland/Germany?
I wanted to do a steam boat island hopping south from The Philippines to Australia. PCs would have been embassy guards or similar trying to get a bunch of non-shooters home alive.
A 'pursuit fleet' would be generated that I hadn't fleshed out but they'd try and stop the ship from getting to Australia by any means possible. They'd be too tough to attack directly.
