I like achievements. I just like seeing that little popup after I do something. It's like the game giving me a round of applause. I don't care for getting all of them or anything like that.

Well, yes, enough that gamification snuck into other sectors. That said, implementation isn't always great, but at least in HK/SS (games focused on exploration and collection of upgrades) achievements are a popular acknowledgement of that collectathon.

I get too much anxiety to chase after speed run achievements, though. It's really meant to be up to the users if they care or not.

Sadly yes, I've seen so many people ruin their fun/appreciation of a game because they "needed" to 100% the game

It doesn't even need to be via galaxy. I use heroic games launcher, and logging into gogs site still shows all my recent achievements.

I think the only pre-requisite is that you install via their API rather than the offline installers they offer. (Which both galaxy and heroic do, I'm assuming lutris too? Tho haven't checked it personally).

It's been a while since I used their app but I vaguely remember some support (?). Although at that point you're basically using GoG as DRM, but I appreciate the attempt to give Steam competition in that space. The whole concept of meta gaming in general is kind of monopolized.

GOG does have regional prices though? Or am I mistaken? I believe it's not for every single currency, but unless I'm completely wrong it's there.
