Capture the Flag!

[Captain Jason]

I love this idea, except i was think more of a reward type thing, one team sets up a skull chest anywhere they choose on their half of the island. Same rules apply as yours, except the goal is to get the stuff in the chest. The other team decides if what they put in was fair and then the game begins. you have to get the objects and come back to win, you get the objects or gold and the game ends. no timer.

I like the land and sea one too, but it would give one team an unfair advantage depending on the ships they had, what if someone with mastered windcatcher, ramming speed, and full sail on a light sloop comes along? hard to hit and traveling at impossible speeds, they just need some high levels with quick foot to win, so what if we all had to use the same type of ship? we could have three types of ships for each team, war frigate, war galleon, and war sloop.
