Back in the '90s, Hanna-Barbera produced a fantastic cartoon called The Pirates of Dark Water. This was a pirate-themed fantasy adventurers on the alien world of Mer. It had the look of an '80s cartoon, and the budding maturity of a '90s cartoon. If you have never seen this show, you have no idea what you been missing. As neat as the characters and stores were, the real draw to role-players is the setting and all the strange trapping there in.
Awhile back, I found a site with role-playing materials about the game. The funny thing is, it was a real RPG book. SOMEONE ACTUALLY MADE AN OFFICIAL ROLE-PLAYING GAME OF THE CARTOON, AND IT WAS ILLUSTRATED JAMES "FUCKING" HOLLOWAY!!! That is awesome, and yet, its not that well known. Its almost tragic, as it is full of strange and exotic stuff, and a grate diversion from all the bland old Tolkienesque dungeon crawls.
Well, I almost forgot about it after a big move, until I was going through by old backup files (I download and hoard so much shit), and I found the PDF source book. Here is the World Book, a download (no pictures), and the Monster Stats. I have to note that this is not a system I would personally use - if anything, its best to cherry-pick the rules to your own chosen game system.
I'm also going to contribute this added info to the Pirates of Dark Water Wiki.
