I feel that this is also important to reitterate.
The morality of pirate ganking at Windows Central
On the topic of mechanical skills, accessibility, and crew-based play, some have expressed concerns how easy it is to grief other players in this game, killing them over and over, stealing their chests, and so on. Is that sort of play "okay" in Sea of Thieves?
"It's an interesting contrast. On one hand, what we're saying is that we want to be the most welcoming and inclusive multiplayer game ever – on the other hand, we're giving you this rich immersive world where you can step in and roleplay "pirates" with your friends. We've made decisions where all quest rewards are physical, and all of that stuff is never truly yours until you get back to the outpost. We believe in the paranoia of having that stuff on the ship because you know that someone can come and take it."
"We've deliberately said that we don't want to have safe zones – that's why we give you a spyglass – that's why we put the right number of outposts around the world so you've got the choice. Can I see masts there? Do I go there? Is there gonna be people there? All that paranoia is what leads to the drama, that "high high." To have that "high high" you've got to have the "low low." One of the things we've strived to do early on strikes the right balance of "loss." "
"Some of the multiplayer survival games we were looking at previously – such as DayZ and Rust – they had that drama, but the lows were so cripplingly low, you'd play for hours and hours and might lose absolutely everything. For us, we feel that we've struck the right balance for our game – yes you'll feel a sense of loss, which I feel is critical to a game where you'll feel a wide range of emotions. You don't want it to be this pure power fantasy where you're never getting better – you want to feel that you've bonded with your ship, and feel something as it sinks below the waves. You want to feel like it's part of the adventure."
"That said, we'll try to do everything in our power to get your adventure going again. Yes, you may lose the chests on the ship, we're not going to take your accrued gold away, anything you've purchased away, or your voyages, or your reputation. All we're going to take are the deferred gold locked in the chest, bounty skulls, or animals, that feels like the right balance to ensure that you've got that paranoia that we treasure, you've got the pirate story, scanning the horizon all the time trying to look for potential enemy sails."
Edit: Oops, almost forgot an important paragraph. I didn't edit this one for brevity, because this topic requires a more lengthy answer in my opinion. Sorry!
