A custom map that starts off completely blank. Each player will get to choose 1 continent from any map they own, and then place it on the map according to their turn order. The continents in their original map have various entry points, and these points would be forced to connect to at least 1 other point on the new map continents. After 1 round of this, if blizzards are on then those will generate. And the game will really start with the auto or manual placement. This would be such a fun mode, and likely encourage map buying. People have wanted a custom map option for a long time. This would be a good way to do it and avoid copyright/ moderation struggles.
