Yesterday I tried a game with a friend, on the Great Britain map (self printed, I do only have the USA original maps) combining:
- The tower
- Princess and dragon
- The plague
- Besiegers
- The catapult, using only knock-out tockens
- La Porxada
- The peasant revolt
- The barber-surgeons
- Without the base game because that would have been too many tiles
- GQ11 to increase a bit the number of tiles
And I'm too sad I forgot the crop circles, Solovei Razboynik, Vodyanoy and the wheel of fortune (why not the wind rose?), for a little more mess, instead of GQ11

Anyway, this was soo difficult to keep a meeple in place, and to find any good spot to place a tile (there was either the dragon, either a plague, either a tower everywhere (or all the three of them!), and always a chance that the other player'd have a tile to place near your meeple (almost every tiles were bad !).
But it was such a mess that it became really funny to play ! It looked more like a survival game, trying to get every little point possible before dying, being captured, or going in a bathhouse.
Some towers were used mainly to take a meeple back from a bathhouse, and the plague was sometimes used for that purpose too.
Only two players with about 90 tiles, but we couldn't reach more than 134 points !

Here's a little picture, where you can also see my new bathhouse markers and plague tokens in action.
