Like the original single-player map, this features pirates- now patrolling the seas. Some rivers have been given shallows so that each player has a pathway to one another, which balances the map for multiplayer use. It also has a basic environment cycle, and some more embellishment, etc!!
Player locations (also in the readme):
1: Venezuela
2: Peru
3: Argentina
4: East Brazil
If you like map-making (including rms)- try my forests!
