Q: Are there special contents at the sea?
A: Every player needs to ride on a ship to go to other continents. The ship does not limit the movement, but it's a good option. There are great monsters which can be only found at sea, so you can choose to hunt it down by riding on the ships. There is practically no limit in PvPing at the sea with no laws. If castle siege takes place near water, ships can be used in the war then. The ship is currently a player's item. There was feedback about sea trade, but there are problems with that, since the ship is technically a summoned item. You will need to unload cargo when you unsummon the ship, and that is unconvenient, so we did not consider implementing that. However, we considered stealing materials, items, and salvaging ships to take some money.
Q: What's a pirate?
A: If you kill a friendly player, which is on your faction side many times, you increase your crime output. If it goes beyond a certain rate, you will start belonging to the "pirate" side. Pirates are enemies to everyone else, and anyone can attack them with no penalty, and vice-versa. Pirates are more like a 3rd side, which is at war with everyone, so we will make special places, where the pirates can live. Usually, you need to enter a special mode to kill allied players (activating PvP status by clicking a button to start damaging them), but pirates can attack anyone without activating any status.
So basically, if you go around and pirate enough you will be moved to a special 3rd faction that is allowed to kill anyone and be killed by anyone. Sounds like it could be pretty interesting, though it would probably limit the amount of "legit" things you could do. Can't very well take a nice stroll through a neat town if you'll have a big target on your back.
