Do you have any? What games are you ashamed of? Why do you deny paternity?

A lot of mine are from a "blind bag style" promotion for Saint Patrick's day, a few years ago. You had to purchase St Patrick hats without knowing what game was inside. I thought it was fun and I, naturally, got carried away.

with the exception of "softporn adventure" we will all note. ;)

I just hide all the demos and the extra versions of games I won't play like some iterations of TIE Fighter and X-Wing and outdated versions like Divine Divinity Classic and Wasteland Non-Director's Cut.

No need to hide anything else because I don't give two flying fucks about what anyone else may think about what I own or play.

I have 18 hidden games. I'll go though why.
Another World 20th Aniv Edition: The game has not been changed in 20+ years and consequently, with no randomization or factors to keep it fresh, once you've seen a video of it, you've literally seen what it has to offer. (I never was into the Dragon's Lair type of games.) Plus, I wasn't ever keen on the graphical style in the first place. Comes with growing up with a SNES instead of a Mega Drive.

Block'hood: The game is dead and I don't want to be reminded that it exists; it was a failed idea. I'll unhide it should the developer bother to ever finish it.

Caves of Qud: Rejecting a glowing review and genuinely being a game I don't get along with; I should have to stare at the screen to locate the PC.

Eschalon 1 & 2: Hidden due to being a drag of a game. Came out around long after Avernum and yet feels so incredibly shallow. Plus the walking speed was a slog, there were too many stats and most classes seemed to be traps meant to make certain playstyles implausible.

Factorio: Kovorex didn't know when to shut up. And left a radioactive crater. I had already had trouble meshing with Factorio, that simply sealed the deal.

Forager: The lead dev lied about being unaided. I had already deemed the game a pointless, poorly designed game. Had effort actually been put into balancing it against new systems, it might still be played by me.

Hotline Miami 2: Wrong Number Digital Comics: I have no idea how I got this or why I claimed it. It's not a game I'm remotely interested in.

Little Inferno: A bit of a switchup here, it is hidden because I have completed the game several times and feel closure with it.

Luftrausers: The developer never gave us a critical update, so progression is impossible. Thanks, ratfinks.

Race the Sun: I completed the game, and felt there wasn't more to get out of it.

Retro City Rampage DX: This game pulls a rental killer¹ several times while having no excuse for doing so. I like the idea of the game, but there's at least two levels I'd axe completely. Also commits the sin of the sudden genre change. (Also contains several fallen stars as mooching cameos and deadnames; but I stopped caring about this game before those were factors.)

Sid Meier’s Railroads!: It's a bad game and an even worse followup to the Railroad Tycoon series. Actually, I wouldn't call it much of a game, more of a pottering around emulator. With games like Tracks! around, there's literally no reason for it. (HEY, BLUES. I'D LITERALLY BUY THIS IN A HEARTBEAT.)

Slime Rancher: I'd compare it to having to drink a very long stein of cream soda. Once you're past the initial cloying bubbles, all you're left with is a very deep glass of sugar water. It goes flat quickly and the game isn't actually about the slimes (nor the ranching), but exploring the map so you can find out a short story in steps. I bounced off it once I had this realization that the grind wasn't to make the ranch better.

Starbound: Unoptimized garbage made by ex-Terraria devs. Literally only kept on life support by one overgrown mod. Allegedly an Xbox port in the works, but that was two Xboxes ago. Here's a longform video that goes into the bigger elephants. Also, the developers kept implementing half baked features and never finished the implementation of any of them. The 1.0 release was awful and ruined any sense of player agency the game had before.

Teen Agent: Thanks, I literally don't want this! Being a teenager was a confusing part of my life and it's not something I'm interested in being near again.

To The Moon: This isn't a game, it's a four hour movie that could have seriously used an editor.

Windforge: It's a stillborn game, in a similar state to Block'hood, but at least the developers gracefully took it off the air. It didn't play well, was prone to CTDs, and controlled like buttered shoes on ice.

¹Actions meant to prevent a player from advancing beyond a rental period of a game; levels in Toy Story (Mega/SNES) and The Lion King had these.

Demos of games
Goodie packs
Rad Rodgers Legacy build (since I have the 'regular' version)
Shadow Warrior 2013 (have the Direct X 11 Version in my library)
The Witcher 3 (since I got the GotY edtion for free when it released)
Wolfenstein II: The New Colossus German Edition (have the uncensored version in my library)
GWENT (why wouldn't I hide it?)

For me it's either a lot of unwanted demo's or duplicated entries (eg, I have "Planescape Torment" and "System Shock Classic" hidden because I have separate "Planescape Torment: Enhanced Edition" and "System Shock Enhanced Editions" visible that are the ones I use).

Demos and old versions.
ie.
Bioshock <I have remastered>
Shadow Warrior (2013) <I have the new dx11 version>
The Witcher 3 <I have the goty edition>

Demos, which I no longer need. mostly.

Promotional junk. which I got as a free extra along with a purchased games. For example, I never licked neither Serious Sam, nor Postal series. As well as Arena/Daggerfall/TES. But they had been added to my library automatically.

And couple of errors. There are few games, which looked really interesting an appealing to my tastes. But, after some time spent in those, it became obvious that actual gameplay invalidates good first impression completely. And I should've tried a demo first instead of purchasing the game immediately. For exаmple, Deep Sky Derelict.

Demos are the only hidden items in my library. That's not because I don't want to see them but because they are visually getting into my way when browsing it. I wish there was a possibility to have Demos in a separate tab, like movies, to have them out of the way.

Speaking of which, if GOG would add an online player for music and videos with tiles and description for extra content, with the option to download to a local device, it would again be a big step in the right direction. Another benefit is that playing mp3/4/flac online, there is likely lower traffic on their end that if constantly large junks of data have to be downloaded. (If only once in most cases). It's almost guaranteed that customers would then return on a regular basis who otherwise might not. With advertisement sprinkled into the player page, maybe they also buy a game or two while they are here. A clear benefit for GOG in terms of generating more revenue. Galaxy would also be a hot candidate to integrate a player, the streaming part is already in there, so not much extra work to be done, incentivising the use of the client also.

Only Her Story from my library. I got it in one of those "Pay $3 get a random game" promotions. Had zero interest in the game or concept of it (and never understood why people raved about it). I know people were getting refunds on these lucky dip games at the time, but I felt that doing so would be dishonest, so hid it and happily never have to think about it ever again.

For completed games, I just flag them as completed - I don't see a need to hide them.

I did see that you've got some great games on your hidden list though - Riddick Butcher Bay is absolutely amazing.

I hide all the freebies I get from GOG. I keep them apart from the games I actually bought because the latter has a much higher priority for me.

Sometimes I like a freebie enough that I move it out of the hidden folder. Happened with Fantasy General and Total Annihilation.

I agree. When you watch something online, you actually download it every time and play this content from the media storage of your browser.)

I have 73. They are mostly demos, legacy versions, goodies and whatever "Crysis Wars" is supposed to be.

I tag all my hidden games in my database. According to that: 32 demos, 15 obsolete (e.g. BloodRayne originals) are I guess obvious. The rest are 28 games I refuse to play. Some I got via freebies or those old $5 for some random game things gog used to have for major sales. Some I just didn't do enough research on before buying. All but a few were just so bad I couldn't bother playing them any more (the few exceptions were games I had already played enough back in the day, so no need to install/play again).

Notable games include Anachronox (recently praised Thursday Throwback, but for me it's ATB combat and slightly nauseating 3D and part 1 of never), Kerbal Space Program (space sim more than building sim, which annoys me with updates even though it's hidden), Darkest Dungeon (anti-progress, and also annoys me with updates), Moonbase Commander (one of the few games I reviewed, and the only one I left a bad review for),

The interesting aspect of 'Her Story' is how it uses a hyperlinked narrative to weave a detective game in which the player is assumed to analyse, understand, and deduce, rather than being told what to do (go here, talk with this character, find this object, finish the quest). If I recall correctly, 'Her Story' technically has no ending; its structure is built by how the player pieces the story together on his/her own.

I think the reason why that game became so popular was due to the fact that there weren't many (or any) other mainstream videogames which had proposed something similar before. Experimentations with hypertextual storytelling and the like belonged (as far as I know) mostly to digital art circles and exhibitions.

I hope this helps, lol.

P.S: regarding the subject matter, I keep hidden the demos and goodies collections.
