One Piece MMO idea

Ever since I started watching One Piece, I've always had an idea for a One Piece mmo. I think I had the idea mainly because I started watching One Piece around the same time I used to play Runescape, which is also an MMO.
Players start from either four oceans they want to start from and try to progress their way into the Grand Line/ New World. They'll have the ability to have bounties on their head and players can turn in other players for a reward of money or special abilities.
Basically, you explore the world of One Piece added with some fun RPG- style combat. Maybe you can band together with your friends or other players and form a crew and have actual battles with other crews. There could be mini games like the Davy Back Fight. There can also be appearances from notable pirates/ marines from the anime, such as Garp, Luffy, Doflamingo, etc. The pirate ships can also be upgradeable/ customizable.
Throughout the game, you can do side quests and visit many different islands such as Skypeia. Some players can also have the ability to use/ obtain different, unique Devil Fruits. Players have to think twice before eating it because if they do eat it, they'll be stuck with it. Devil Fruits would also be able to be traded/ sold on a marketplace of some sort.
Not only will players have the ability to become pirates, but they can also become Marines, Revolutionaries, Shichibukai, Bounty Hunters, etc. Players would even be able to become Fishmen. Marines can also have the ability to reach top ranks like admiral, but the challenger worthy of Admiral would have to battle the current one for the spot.
Anyways, that's just my idea of an MMO that, if done right, would definitely become a success.

This doesn't belong here.

I think this topic would be better for the Games Discussion page.
