This version of Caribbean lowers the size of player islands and brings more water in-between them.
For the most part, the map is made 75% of its original size, though for 2-3 player games it is made 60% of its original size.
With added distance between islands, 65 instead of 55, there should be more fun in demolishing someone's island rather than just hoping to invade randomly.
Tested and should work with up to 8 players as a custom map.
