MarkoH01: Also, please tell me why you think that
optional^ achievements (all achievements tied to the client are optional) would ever hurt your personal game experience? Yes, achievements you can't switch off (ingame achievements) might do this for some but the usual achievements we are talking about here won't even get noticed from those who don't want them while they are fun for those who want them.
That
might be more arguable if achievements were off by default and one were to have to opt in to them. But that's not how it works. Achievements ruin play experiences all the time, from immersion breaking, to spoilers and similar. They rather often reduce the joy and discovery while playing games. They're also sometimes used by developers as a crutch so they don't have to spend effort to design something better (e.g., "an achievement will point the player in XYZ direction" rather than
the game itself doing that.). And they hurt people who chase them.
Online communities are greatly hurt by "prove you are allowed to talk about this game, share your achievements showing you've platted it" mentality. Which is sadly not uncommon.
People engage longer with titles they should have stopped for one reason or another in the hunt to complete all of the achievements. Often to the their own detriment.
Games with multiplayer achievements have sessions wrecked by people achievement hunting online. And they're usually asking for degenerate activities, too.
And, before you discount people who are compelled to go for all the achievements, don't be an asshole. It's as system explicitly designed* [originally -- and persists] to exploit people into "engaging" with a title longer/in different ways, so that they're not going to competitors titles or keep with a title until the next update or patch lures them back in.
One case study of many: The people whose whole play experience of Stardew Valley is ruined by the Fector's Challenge achievement. It completely fucks up the game for them. Their experience on GOG, where they'd never be introduced to the concept of "I must complete and perfect this mini-game that completely clashes with the overall game".
Another: Blue Dragon's "get classes to max level" achievements. You'll have literally everything else in the game done long, long, long before these. Uncountable games have those like this.
I have gone into greater detail in previous posts; they should be findable by search. But I know you're not interested in engaging in a good faith discussion. I'm glad I am not of the personality to have them drag me through the mud like that. But a member of my household definitely is, as are a few of my friends.
Would gaming be better if the idea of achievements had never been dreamed up? Yes. No one would be missing anything of value, and plenty of people who do have problems created by them would have that problem solved.
* In addition to their design of "drag people in to our ecosystem", which is also their purpose for Galaxy -- something that shouldn't be reinforced.
^ "It's optional" is never an excuse for anything. See also: "it's optional!" for "microtransactions-are-OK" arguers.
