It is so frustrating having a map editor that is nearly usable, just lacking the proverbial ha'porth of tar. Once it is fixed, there are some interesting ideas for extreme scenarios one could try - for instance: A map that is all land, and broken into a number of isolated basins by impassable mountain chains. Each player starts in the centre of a basin. The game is then set so that only domination wins are possible. Each player would be incapable of even meeting the other players until tunnels are discovered! Incidentally, what would happen to the Maori in such a case, with no ocean to start on?
