From publisher blurb:
What if the first RPG was inspired by epic tales of the buccaneers and pirates of the Caribbean? Instead of slogging their way through gloomy dungeons, freebooters hoist the Jolly Roger and seek plunder and adventure on the high seas!
FREEBOOTERS is a pirate-themed retro-clone intended to be compatible with the original fantasy RPG, Raiders, Guardians, Colonial Troopers, Warriors of the Red Planet and others. The rules presented can be used as a complete game or a companion to fantasy games using the same overall system.
