Viking raiders. Kind of like Dark Island and DDay and AoE. Two islands, large bridge which connects them, but both teams hold it so they use boats to raid each other. The teams need to get resources to build a war ship but can steal the other team's resources. Once a team has X amount of wood and iron and wood, the admins reset the boats or something, or drive them in, and they can now raid the other team. The objective would be to build a boat first, then obliterate the enemy team. Includes build-able forts, wildlife and such.
