Deleted

Yes I did, and I will continue cleaning up my library.
But I think this "permanently" is a lie :D
As far as I know you can restore those removed games later, so they are not deleted permanently. Your playtime and achievement records are preserved as well. Only Steam support can truly remove your games completely.

I once asked support to delete a game from my acc way before it was "normal to do so" and they did it manually. It was a copy of a game I got in "coal" trade but ended up being for another region so I couldn't buy dlc or anything (and no, I didn't use vpn, it looked normal and activated normally and I could play but just couldn't buy any dlc)

Yes.

Yes, about 100 of them (played / tried every one before deciding to delete them too).

I just made a folder in steam called "low effort" and dumped everything there. I dont want to get rid of them, I like them.

No, cause I don't feel a need to do so.
Especially more so for the stuff I win.

A hundred or more from my main account (over 1000 from a secondary). Stuff I realised I'd never play or return to finish ever again.

Tons. I used to like +1s, freebies wth cards, and in the early days of bundles, I added everything to my account regardless of interest. I don’t like clutter or keeping things I won’t use, so why not remove the game? I feel WAY less guilty about having 900 games and not playing a bunch than 1600. The fact that I can get it back as easily as I removed it is nice too. I’ve done so once. The only “advantage” to removing over hiding is that your library number actually goes down, and that certainly isn’t an advantage to everyone.

Once upon a time, there was a website called Playfire, which gave you store credit (GMG, I think?) for earning achievements. Sometimes the achievements were for F2P games. One such game was "Everlasting Summer," a visual novel.

I started playing it, and immediately hated it. I won't go into detail, although I will say I don't know why this trash has 93% SteamDB score. People just overwhelmingly like this game.

I didn't play long enough to earn any achievements (Thank goodness--I'd hate to have that hanging over me), but I was so ashamed to have public evidence that I even bothered to play this game that I removed it from my account.

Fast forward a few years, and with madjoki's script for acquiring F2P Steam games, it's back in my account. Oy.

Yea I wanted to buy a bundle, but had one of the games in that bundle, so I had to delete it

Yes. Deleted my Censored German version of Saints Row 2 and replaced it with a global key.

I recently removed two disgaea demos from my libary because everytime I sorted my games with Depressurizer they automatically moved out of the category I put them in.

But no, I have never removed any games.

I got some in this Gold Ticket thingy from Indiegala, which I just... don't want. Buuuuut I still didn't get round to getting rid of them. Also I might just be to lazy to figure out how to do this hides

No, to much bother... It's not like they are taking some space, right?

Never have and probably, never will.
I don't mind the junk or the crappy games. I just ignore them. As for the thinking what some people/friends will think if I own some particular game, never have I cared nor I will ;)
It's your game. You should enjoy it (or not and hide them, delete them etc).

Yes. I bought a game over humble bundle. Which I Absolutely hated. Humblebundle refunded me the money and as a common courtesy, I deleted the game off my steam account.

No, I just hide them.
Being able to prioritize games with library categories has been helpful, too.

as KlappPc said you can't permanently delete them but I have done it to hundreds of games and will continue doing so

No, I have categories for a reason. It's not like I scroll through the list anyway, I normally just use the search bar.

Yes, I've done it with some of them that were just really really reeeeeally trash games

Yep, I've actively deleted about 10 or so games. If I'm definitely never going to play something I'd rather not have to have it taunt me in my library.

I deleted a few because there were "purchase togther" bundles that wouldn't let me buy because I already owned one or more of the games included. So I technically bought those games twice.

One. HITMAN Sniper demo level thing from a free key. Couldn't play it in my region.
