I think emcdona mentioned it, but having a survival island set up in the middle of no where would be cool.
We would have three different types.
1) Two factions fight for resources. To take over the island.
2) To win you must create a raft, and collect the necessary items to get off the boat.
3) To win you must figure out the secret of the island.
Might not be able to do 3 for a long time, but one and two should be in
Rules: Up for editing
No swimming off the island to get supplies, if you just want to build then do it on the normal map.
Faction rules:
No fighting in safe zones.
Must only use claims on built houses.
Two rules:
Must create a 4x6 raft with a sail made of white wool.
A chest filled with 8 cooked pork
8 fish
A fishing rod
A spear (Sword)
Flare gun(Tnt, Bow, and Arrow)
Paddles(2 shovels)
Three rules:
I'll figure them out later.
