The game is Sea of Thieves. Me and a friend did a Skeleton Camp, and after getting the treasure from the room in the screenshot above (worth 20k), we were attacked by these guys who rammed us. They sank our ship before we could get back on, so i spawned the ship back in, raced to pick up my friend. Then i sailed past the outpost, my friend jumped off to sell it while i sailed away as a distraction. Then once all our stuff was sold we hit anchor and attacked them. For a galleon manned by 2 guys, i think we did really well. We still lost but they took on a ton of water and after they sank our ship we went for the old bucket strategy and started filling it with water. It was a lot of fun. Whoever that crew was i owe them thanks for giving us an adventure.
For the most part I would say so, but there are also things more things on the ocean to do. There are also the PoTC and Monkey Island quests, which are much more Story Driven Quests (Idk how new they are though so you may have already played them)
