I recently pre-purchased the Final Fantasy Pixel Remaster series on Steam. I also own the 3D Remakes for Final Fantasy III and Final Fantasy IV. GOG Galaxy correctly recognized the Final Fantasy III pixel remaster and the Final Fantasy III 3D remake as two separate games. For some reason, it has combined the Final Fantasy IV pixel remaster and the Final Fantasy IV 3D remake into one game. It displays like when you own the same game on multiple platforms. Is there any way to undo this and display them separately? I am a stickler for library organization; it is the reason I switched to using GOG Galaxy. So any help with this will be greatly appreciated. I will attach some images to better explain what I am referring to.

Then I suggest you switch to library management software with more features/options, like Launchbox or Playnite, for example.
As to your question: I could be wrong but I don't think you have control over grouping like that in Galaxy. You might only be able to resolve this by contacting GOG about it.

Me, I like Launchbox best. If you want something with the best database features (but not really intended to be a Launcher), have a look at Game Collector (Collectorz). It doesn't import accounts though, so there's a lot of manual labour involved.

Galaxy is foremost a "client", not intended to give its users as much control as possible.

I was afraid that was going to be the answer as I have already extensively searched for a solution to this problem and this post was the last resort to find an answer. Maybe I will give Launchbox a second go, I didn't enjoy it last time I used it, but that was a while ago.

What part(s) of Launchbox didn't you like? (maybe I can tell you if it has changed since then)

I really don't like the default theme. It looks like you can change the theme with a premium license. I wish there was a trial version of the premium so I could try it out and mess around with the themes. Maybe there are some videos out there showcasing some of the better themes?

I don't think that it looks that different from Galaxy (see attached screenshot, it's the default theme).

Just a minor note, neither are really library management except as a secondary consequence. They are launchers. Library management is something a bit different, like collectorz.com. There is t much on that front. Playnite would be better at that if they ever release v9 with a proper database backend, then you can import/export and utilise the data (and stop out all the connectors to stores) etc.

Semantics aside, I definitely want a solution that is a launcher and helps keeps my collection organized. Or I guess a better way to put it would be to say a launcher that displays my collection in an organized manner. And I want something that is pleasant to look at, which is obviously subjective, so flexibility in that area is appreciated. GOG Galaxy is definitely lacking on theme customization and offers no ability to edit meta data. But up till now I had not run into any deal breakers, and I love the default look of the launcher. This issue is frustrating enough that I'm considering other options.

It depends on your expectations.
If Launchbox can do all or most of what you expect from library management software, then its original intended use becomes pretty irrelevant.
What's wrong with connectors to stores? You use them to get the data locally (if that's wat you want) in an easy way. Does their presence bother you? Is there a downside to it?
If Launchbox had a GOG import function years ago, I would've never bothered with Game Collector. It's extra features aren't worth all the manual work I've had to put in. Because of that import function, my games all have some nice screenshots. I don't even want to think about the crazy amount of work I'd have to put in to have the same in Game Collector.
A few years ago, I asked the Game Collector developer to implement "embedding" local videos (trailers, etc). The answer I got: Never going to happen - because he thinks that "nobody's interested in it". What I think: Collectorz wants to focus on "software as a service", and adding more offline features isn't in their interest.

If you are happy with galaxy mostly, then one of those two would be fine. Playnite is free of course, launchbox comes in two versions. In terms of metadata entry, well, neither of those offer great metadata entry, as they are built as launchers, you can’t add extra library fields and such like. I also don’t know about backend access to launchbox (say you want the metadata for something else), now playnite currently stores it in loads of Jason files which is fine for the software, but useless for other things. The version 9 has a proper database file which can be accessed in c# programs. I like to check my metadata against folder structure for instance. But yes, try playnite, you have nothing to lose there. Of course, if your expectations match then fine. I have no need of a launcher, I don’t have everything installed, etc. And as a database it’s far from useful.
Yes, I don’t want software that has connectors in it, wasted space and functionality. I want an organiser, nothing more, no launcher, no store linker, no fb integration etc. I wouldn’t trust metadata from a store. Also, if like me you have been building it up over decades, I have a ton of metadata that’s unique to me.
Collectorz I used for some years, but it’s proprietary nature makes it mostly useless, no real export features, no backend access. And yes, they are online mostly now, so I ditched it.
Currently using a spreadsheet, if I ever get time, will build my own database.


Do note, playnite doesn’t allow you much if anything in the way of user fields, different grouping elements and such like. Don’t know about launchbox, tried it a while back but can’t remember much about it as it was only interested in things I had installed,

Launchbox has custom fields. What other kind of metadata entry are you missing?
Sure, more options like import/export (txt/csv/html) is always good to have (I don't need it ATM/anymore... but there's no one program to rule them all. ;-)

Edit: User controlled grouping in LB works really well (and is non-existing in Collectorz).

This is obviously a glitch GOG should be informed about. From Galaxy select "inform about a problem" to open a ticket from the upperleft icon. When in the past I had simlar problems in the libray they were solved eventually.

But the forum is not the ideal place to do this because it is a hit or miss.

Well,launchbox didn’t when I looked at it some time back. And I know that playnite doesn’t really have that, or plans for it (I asked on their forum). Of course there is no one program to rule them all, actually there is excel, which I hate to say is better than most things I have looked at, what does that say for the state the market in that area. Anyways, I have a very specific files structure setup and I like my metadata to follow this, so extra field ps and concatenation of fields is useful. Take lego for instance, lots of lego games, some are LoTR, LOTR can be split by various groupings, but hobbit and LOTR would be one. Then there is marvel, but batman would be a subcategory. Etc. It may be better in launchbox now, I don’t know. Asked some questions back when and it’s was all no go, only for launching things that are installed.
