Alternate planet map by ''The cewltonians.'' Features a medium size map and very powerful bonuses that vary based on climate. Designed in a manner similar to earth, but with unfamiliar details in places. The map is great for a 4 player brawl or for a diplomacy experience with 6-20 players.
Note that the game is not designed to be balanced, as some regions are simply richer than others. For a more fair game, try using the 'Habitable Areas' distribution, and make the non-habitable areas extra strong neutrals.
