Am I Too Old To Be A Pirate?

[Basil Dreadflint]

As Max and Zep said, There are many adult players. Check out the guild forums and see what attracts you. There are quite a few guilds that are mix, adult and younger, and there are a few that are adult only.

There are at least 3 in the general guild forums that advertise as adult only.

Never sail to the end of the world, it just tells you to turn around!
Sound advice.

There are some tricks too. Right at the end of school hours, the preteen and teens tend to be more prominent.
The other trick is to learn which servers tend to be filled with the younger players. They become obvious as you play the game.

Good-luck in your endeavors.
