I’m not sure that’s possible with multiplayer games, at least the central server part. They could release the central server code as an open source project… that would be very useful. But MMOs need that central communication to even work. I mean I guess you could engineer some sort of peer to peer but I’ve dealt with weird firewall rules in various DCs I’ve had servers located in or god forbid the lack of incoming connectivity in peoples homes. Outbound traffic is usually fairly unrestricted so a publicly available server is the way to go architecturally.

How dare you have a reasonable response when we all just wanna be pissed. /s
But seriously some people should just not interact with the public. It’s a thankless job and you have to have very thick skin and the patience of a saint. I also have a theory that a large percentage of CEOs are sociopaths/psychopaths so …

But what they don’t take into account is that 75% all at once creates an excitement buzz around the game that ends up causing even more sales then would ever happen otherwise. Look at games like Pokémon go or PalWorld that generated so much buzz. I tried both of them because of the hype and I normally wouldn’t have bothered otherwise.

And even then it’s sometimes impossible because how much can you keep in your head at once. Everybody specializes on these large projects. I may have 30000 ft view of how things operate but getting down into specifics can be hard. I have some intimate knowledge of the learning management system we develop for, which is way less complex than most games, and there are always little gotchas when you make code or architecture changes.
Achievements basically boil down to “does it matter to me that other people see that I’ve accomplished something” and that only matters “if it matters to other people that my achievements are worth knowing”. It’s essentially trying to generate interest in a game by creating this social competition and of course FOMO. So I guess it’s just social media advertising.
In my case none of this matters. I play mostly single player games because I enjoy them, not because I care what other people think. Having that info in game is sometimes cool if I want to know I’ve finished everything there is to finish.
From a game developers standpoint this data could be useful. Is this part being used? How long does it take? At what part in the game did they accomplish it? That sorta thing. The publishing of that data in a public space is different beast.
