It's not like ROSE. It's quite different. Well, theres only 4 characters you can choose and it's a fixed job/sex.

Well, it's does sort of have that pirate theme. The NPC's are also pirates and stuff. Also there is ships, and if you are explorer (class - reccommended if you're rich since if ur poor, its gonna be hard) you can fight while ur in a ship.

I played up to lvl 40 cleric (job adv.) and you need to party a lot if u want to lvl efficiently.
