Cavalier Gothic is a GURPS 4E Age of Sail campaign set late in TL 4. An expert knowledge of the rules is not required but some familiarity with the system is a must, and you really ought to have access to the Basic Set (or at least Rules Lite). GURPS Swashbucklers, Martial Arts, Low Tech and Horror will also be useful.

The game is cinematic by default, hopefully capturing some of that old swashbuckling feel that Errol Flynn would be proud of. Play style will be mostly plot-driven, but with plenty of open world sandbox time as the game goes along. The campaign will focus on the exploits of the party whether that means tooling across the ocean in a pirate ship, exploring the untamed forests and jungles of the New World, or participating in the struggles of the Old. Characters will be encouraged to travel where their interests, abilities and obligations take them, but should expect that some sort of adventure will await them wherever they go. The overall tone of the game is serious, but with occasional light-hearted scenes.
