The assasin's Creed games might be a great source to help with thinking of details for a medieval city layout, with all kinds of little details to give inspiration. And my condolences to the poor clickies that drowned in that flood.
Well in 1997 there was a flood and all the playmobili had in a similar basement were washed away . i was lucky that a few months before some were taken elsewhere, i lost however lots of klickies, most modern /construction i had, all space, some pirates and various other toys, so i guess no matter what there is always a risk and a downside .
Days? I'd never get over it!
At least the pirate clickies might get away safely on their floating pirate ships.
