Tortuga:
Moving the convo here, what do you guys consider necessary for a golden age of piracy game? Is it about a specific historical era, or a certain mood or tone?
That's actually a pretty interesting question. For most of us the mental Imagee conjured when we hear the word "pirates" is the hollywood version: Douglas Fairbanks, Errol Flynn, and more recently Johnny Depp swashbuckling (or in the latters case swishbuckling) they're way across the silverscreen.
Now nominally these flicks are set in some vaguely defined age of sail period somewhere between the reign of Elizabeth I and the early 1800s, but they are pretty much all ragingly ahistorical, even the ones not based on a themepark ride. It's all about costumes and tropes, not dates and historic fidelity.
If you happen to be of a more literary bend and had you're idea of pirates shaped by Sabatini, Stevenson, O'Brian, and Forrester chances are it has a bit more fact than fantasy and you'd probably care for a setting at least roughly matching the timeperiod and locals during which piracy and it's most infamous practitioners flourished.
Lastly there are your history nerds. They'd care about realism, but somewhat ironically might be the most agnostic on the game being set in a specific time period or place so long as the details are historically accurate. Afterall pirate utopias bloomed in many places over the centuries, not just the 18th ct caribbean.
Personally i fall somwhere inbetween (the cracks?). My primary concern would be that the setting has internal logic insofar that it's economic and polital sitution would meet the neccessary criteria for pirates to exist. Beyond that it could be japanese wako riding the cbinese coast, english privateers sailing out of Port Royal to attack the spanish indies, or H.Beam Piper's space vikings nuking Amaterasu from orbit to loot their gadolinium stores.
