Pirates of the carabian online...
sounds a bit farfetched but it isnt
is a mmorg:
u create and customize ur character, get a sword,gun and the fun begins
u complete quests, join crews and buy ships where u can sail the seas attacking other ships and firing cannons at them, and even board other ships and plunder their chests,
and as if you need anything else to make it 100 times better then WOW (never played and dont intent too) is it is free, although you can pay £2
which would unlock new ships, and play games suck as poker etc it is a really good game and have been playing it loads lately, anyone who joins let me know and we can meet up
