AFAIK, there's nothing preventing YOU to create a game-specific thread for any game not sold on GOG.

In that regard, may I remind you of all the threads about "which (indie) games would you like to see released on GOG", etc?

It's really not as if those threads don't exist.
Of course, you can hardly expect GOG to create those.

Edit: typo

I mean the threads I show in the attached picture. I really didn't know anyone could create these! I thought only staff can create these, when the bring a new game in their catalogue!

I see. Those are created by GOG.
And as I said: you can hardly expect GOG to create such threads for games NOT SOLD on GOG.
What would be the gain for them in doing so?
Apart from the unnecessary workload? They can't keep up with their regular work.

Those sub-forums (not threads) are more specifically for support. GOG only provide support for the games they sell.

You can create any thread in the general forum for any game people want to talk about, including games not sold on GOG.

Thank you both. I hope at least my second question can be implemented. To each game in our wishlist could have a separate (could be drop-down) menu, where one would be able to choose to receive email about this specific game being on sale, independently of others being on sale.

1 thread with gta, dvd, and emulators is there.... https://www.gog.com/forum/unreal_series#1748061776 so as delisted games, your wish travelled back in time
2 some info about new releases can be sourced here https://www.gamespress.com/, as for individual emails who knows : )

If this is a game of "two ideas" then here I GOG

I want GOG Radio, a mix of craziness and seriousness in the video game world,
where two girls interview guests a day
and a Noble person testing game a week.

It wasn't my attention to start a game, I was genuinely asking!
For the second question, I meant that, instead of checking the box “Wishlist alerts - Sent whenever games from your wishlist are on sale”, which sends us emails about all of the games in our wishlist, when some of them happen to be on sale, to be able to ask for said email when specific (isolated) games from our wishlist happen to be on sale (instead of uncontrollably all of them).

Purposely or not you made it interesting with the name of this thread : D

I get what you say about this email. It's happened for me to receive email with only one game, too, but normally, it comes in multipacks of many.

I find this very confusing.

Why do people not understand what a forum is, what a subforum is, and what a thread is ?

A forum is a place like this one. A forum usually has subforums. We are currently in the global subforum. Any game GoG sells, there is a subforum for them. GoG obviously wont create a subforum for games they dont sell; that would be extra work they dont get paid for and would lead to complaints. And within the subforums you can open threads, which consists of posts.

It was already confusing when people suddenly called threads "forum", which I have seen recently quite a lot. I mean I totally accept "topic" instead of thread, since every thread has its own title, and a starting post, thus every thread has a topic, so you can call the thread topic and in most contexts thats precise enough.

But now people call subforums "threads", too ? Even more confusion ?

This is as confusing as people calling star systems "Galaxy", as I've seen many people do in "No Man's Sky". Though at least there nobody ever called a galaxy a star system.

I guess one could interpret a thread as a very simple and very primitive forum of its own. Thats not precise at all of course, but its not totally unlogical. But calling a thread a forum makes no sense at all. A thread is a connected stream of posts. A forum has different threads each with its own topic. So it definitely a forum cant be confused with a thread, and cant be interepreted as a thread.

You are right. I called the subforums, as threads. So, for me it is (the overall) forum – game-specific threads – topics – posts.

Thats how its been for the past 30 years, and until recently I never saw anyone question it, yes.

My (admittedly not terribly useful) answer: yes it could, but it likely won't happen because that would be too much work for GOG.
Heck, while we're at it, we could even envisage a system analogous to isthereanydeal, where you could set a maximum price, or minimum discount, to receive notifications. But this is even less likely.

Not to knock your idea - it's a valid suggestion - but it notoriously takes GOG ages to change anything and if the changes are finally implemented, it's usually stuff that noone even knew we needed (in diplomatic terms), instead of the things forum users have been asking for, for years on end. You'd be better off to just use isthereanydeal.com for it. That site even allows you to individually define the price/discount at which you'd like to be informed.

No, all game specific forums remain even if the game gets delisted. Some of them are actually active with new posts, too.
