Terra dei Demoni

If you include an underground, the essence of the map will be lost, although it might be possible to divide the underground as well? (I doubt it, to be honest). It's clear that you can generate things, but the tournament is played on a standard map.

When playing with an underground, the map is divided in exactly the same way, only some of the zones may move into the underground (secondary zones - Dungeon and Inferno zones).

Regarding the size - I won't object if someone wants to play future games on a different size.
