Earth, but inverted so that water is land and land is water.
There are 41 main bonuses in this map, with 6 combination bonuses that replace two smaller bonuses. As a result. the map can be played with 35-41 non-overlapping bonuses. Changing the bonuses, as well as their values, can change the value of the map.
Good map and a neat concept. I might recommend leaving more room around the margins as I'd like to be able to have more space on the top and bottom and because the wraparound feature you use, while cool, is pretty distracting at first.
