Rejenorst must, say you have some excellent Ideas!
I've also got an idea, this is more based for Naval
Right so, allow me to begin, it would start off with each team having 3 boats, 2 of the boats being defending boats armed with cannons ect. the last boat in the convoy is a small ship full off goods and armor the objective of the 2 teams is to attempt to board and take over the other teams Goodie Boat.
