Fine, i'll tell you how you then should do it.

1) go to the search section and find your 'horror' games (or whatever tag you want)
2) write down all the games, especially ones marked 'owned'.
3) Go to your games, make a new tag call it 'horror' (or whatever tag you want to go with)
4) Find all games you wrote down, likely searching one by one
5) Manually add tag of 'horror' (or whatever tag you want).

Poof! Problem solved. Now rinse and repeat for likely all 100 tags that you want or care about.

Unless someone at GoG allows some simpler functionality, it's probably not going to work.

Personally the 'tags' i put in for my games are 'completed' and 'free/giveawa' and 'this game sucks', etc. I don't bother with genres or tags that are already in the store. Plus there's a number of games i don't care for, including horror games.

As for replying and blocking, all you have to do is ignore me. If you reply, it suggests to me you want to keep the conversation going. Believe it or not, you are the only one seemingly complaining.

Actually your post supports the request to be able to filter by store tags.

It shows quite impressive, how bad our user tag system is.
With over 2000 games and multiple possible tags this could take a few weeks.

We don't even have multi selection in our tag management, it's just awful.


That's where you are mistaken. Questions about improvements to the tag systems keep coming up, there are also some entries in the wishlist about it.

... and we didn't even start to talk about Galaxy, where it's even worse, starting with the fact that the homepage and the list in Galaxy don't share tags, they are not synchronized it. And in Galaxy you can't even delete or rename them.

I do agree we should be able to use the innate tags present. And since i can't make the changes myself i can only pine and wish about what i COULD do. But since i can't...

A what? Never seen that word before. But doesn't matter.

Because that's the only way i see it working at present, unless they actually do something. But if you don't want to use what's currently available by all means do it however you want.

Soooo... what's the problem?

Not to defend GoG or anything, but the slow upgrades over time and artifacts of the original code are definitely showing, from when you could rearrange your games on the shelf to any order you wanted.

As a programmer they have the store and the user dashboard completely separated, making user tags their own thing (and likely their own tables too), while store tags are for the store. Not confusing. The tags would require a userID, the gameID, and the tagID. It was probably originally seen as tacky as importing tags for every game with their original, especially if people were deleting them and wanting to put their own stuff like 'first game played in 1990' or something else. Did that happen or were tags added in the last couple years? I am not sure. I don't remember user tags when i joined in 2013. Rather than doing a lot of work that may mean nothing, it's easier to leave it blank.

With the various forum bugs, like new threads not having italics button, to wanted features, GoG probably has a skeleton crew who are likely swamped with tickets, and the 'if it's not broke don't fix it' is paramount. On top of that, anything that may involve user data (and accidentally screwing accounts up, owned games or user data) would likely need extra scrutiny, or possibly only one person is authorized to touch it. No doubt the tables and database is a headache as it is.

I'll say it again. If i could fix it for you, i would.
