Well, this is just ridiculous. A group playing at GothCon in Sweden earlier this year set a world record for the biggest ever game of Carcassone, assembling a board made out of 10,007 tiles.
The game was put together by Paul from Carcassone Central, and was inspired by a digital mock-up he made showing *hahaha* a game with 10,000 tiles *hahaha* as if that would ever happen.
Until, you know, it did. Paul's in the middle of writing a nice recap of the game (and the prep work behind it) over on Carcassone Central, but you can see the completed game — 108 x 92 — in the video below.
