The placement map measures 11 inches by 17 inches with a 1/4 inch margin around the edge.
To save on some space, I had some of the hero/rewards cards overlap.
There are two places for development cards, one for unused cards on the bottom center, and four on the right for developments in play. If you managed to get more than four developments (or more than three title cards) then I authorize you to go to your local sticker store, buy some gold stars, and stick it to yourself on the center of your forehead.
Critiques, good or bad, are welcome.
