@ethnine I've also noticed the increasing mention of the 'Golden Age' and here's my interpretation:
If you think of piracy per se, it's been around throughout recorded history and before, but there are particular periods where conditions existed such that it could flourish. The establishment of colonies and trade routes from the New World to the Old in particular during the 18th century.
If there was nothing to plunder, pirates would have no prey. The rich merchant ships, the Spanish treasure fleets, the horde of disaffected ex sailors and privateers all provided the conditions for piracy to flourish and the Caribbean and then the Indian Ocean with their lack of 'civilised' law and order, became their playground. A great many of our favourite pirate legends, fictional and non fiction come from this era. Pirates of the Caribbean, Treasure Island, Blackbeard, Sam Bellamy, Sir Francis Drake etc.
So if we transfer this to Sea of Thieves - this is our own world; we're here in a newly discovered area of islands, poor on the surface but with secrets, lore and treasures as well as incoming Trading Companies who reflect that search for new sources and markets in history and who provide motivation and sources of wealth for us. Maybe we're even a bit disaffected by existing worlds and games and seeking new opportunities, or am I taking the analogy too far here... ;) Sea of Thieves is also a fantastical world and one not accessible by everyone, like avalon or other mythical places and this allows for the likes of the kraken and potions as well as effects and experiences that are found in fantasy fiction too, it makes the experience all that more richer.
There are also other pirates sailing the seas, those discovering hidden wealth, exploring, trading and plundering - that's us. Some of us will become Legends, some of our stories will be written and shared, our fame will grow by word of mouth and our accomplishments become widely known.
Rare have told us that Trading Companies will come and go, the world will be mobile, it will be living and not static and this will also create new stories and adventures, motivations and styles of play.
Also, we know the Golden Age did end - circumstances changed, the governments of the world clamped down on piracy and it died down once again. Sea of Thieves has a road map for 10 years? I think that's a good long time for a new Golden Age and it's ours.
