Segregation in Carcassonne!
You've mixed all your Carcassonne expansions together for the massive, every-expansion game. Now you want to separate them to try a simple mix of no expansions, or only one with the original. How are you going to tackle this daunting task? Easy! Look at the photos in this inventory, and parse the tiles appropriately. (I recommend focusing on the expansions, and letting the original Carcassonne's 72 tiles remain as the distillate.)
