I've done the following:
>Randomized map orientations (players can start in any corner of the map)
>Significantly more land on the sides
>Fixed bugs in the objects_generation section
>Slightly more trees and gold/stone/berries
>Slightly larger central islands
>Removed the elevation_generation section because it was not working at all
>More trees on starting islands
>Added transport ship
Also, I added support for all game versions
