PVE game
More and more powerful things to attain through pve you do not even have to change its appears much and people will still value it. Cosmetics are inefficient cost wise as they are subjectively interesting as they do not provide any real benefit to the players. The exception was the new Athena sails that have holes making it somewhat advantageous to use.
PVE players are probably the most expensive to keep happy as you have to keep producing content for them to consume. The game is all about consuming content for them rather than competing with others at a core game like pvp.
PVP
Just killing people for the sake of killing them without stats or some way to measure your success relative to your peers is uninteresting after the novelty of the game play wears off. Most games that are very successful have clear winners and losers along with a ladder to track your progress relative to other players. These games are very cost efficient for example chess and elo. Very inexpensive to implement but millions play it with literally no content updates required. To me chess is one of the most cost efficient games ever created.
Sea of Theives is a strange title in that it is a pvp game trying to be a pve game.I say it is a pvp game because if we used its ruleset in any mmo it would be considered a pvp server. Sure you can make friends with everyone but at its core it is a semi hardcore pvp game. It is not hardcore because you cannot steal players existing assets only newly acquired ones. It also has about as many quests and pve activities as leveling from 1 to level 10 in world of warcraft for just one faction.
The developers to me are continually making the mistake of listening to the pve players. They are blackhole budget wise, they consume content quickly and they want more and more things to consume , only satisfied briefly and then leave to maybe come back if they haven't found a new shiny carrot to chase. The only way to really keep these players for longer periods cost effectively is to have the grind for power items that give advantages so that they can grind for even more powerful items faster.
I think the best way to make this game survive in the longer term and keep players paying and subscribing is to add competitive systems to this game. I know the pve players wont like it, but I do not see them focusing on this game having power item farming or endless supply of funds for lets face it very quickly consumed content patches. I will added these patches so far incentivise players come back to get meaningless cosmetics at the price of playing a hit and miss pve content with fewer and fewer player returning every time.
Players need progression as much as they need to create great stories in this game. In most cases the reason those great stories happen is because they were trying to progress in something that would give them an advantage. This game allows you to progress every 5 levels allowing you to farm better and better loot. This is not enough though as the content is just too sparse and creating the amount of content needed to will take several years and by then everyone will be pl already and some tiny player base still playing this game will be the only beneficiaries of this work. Competitive progression games amongst players in pve and pvp is to me what would serve this game better. Players compete for standings and get rewarded for reaching a certain standing is a great way to keep players playing while not having pump out more and more content for them in such a forced way.
