Even Bad Rats?

Yes. After all, even bad media can be used for parody, retrospectives, speculation of lost opportunities, or examples of how to engineer something better.

If I could add an entire genre of games I don't want to see on GOG, I would choose any of the recent multiplayer only games that have come out in the past year or so. Especially since the price is still 60 dollars, sometimes more, when you would think that they could could cut the price in half since there is no single player campaign to speak of anymore.

But The Incredible Machine did it correctly ages ago. If anything should be made retrospective of...

I don't see the conflict. If anything, Bad Rats, The Incredible Machine, and Contraption Maker can be compared and analyzed with each other.

Good things do not exist in a vacuum. More often than not, the best creations stem from understanding why something does and doesn't work. By excising "negative" content from existence, the ability to learn from mistakes is compromised.

Then you'd be discounting games like unreal tournament or quake 3 that are multiplayer only as well. The only reason why they are so cheap on gog is because they are 10+ years old, but back in the day they were 60 doller games too. Same with counter strike and battlefield.

As long as they have quality content, lan support and allow private servers I say theres nothing wrong with them.

I don't want any more Win7/8/10-only games on this site, especcially when they're OLD.
Making old games (well, their "enhanced editions" like with System Shock, Grandia 2 or Turok) exclusively available to a very few modern and heavily DRM loaded operating systems is bad.
Times have changed, many former Win98/WinXP users migrated outside of the M$-realm and even Steam has accepted that and is supporting it.

I don't want any games on GOG. Games are the path to the dark side. Buying games leads to guilt not playing them. Guilt leads to anger, anger leads to hate, hate leads to trolling, trolling leads to long and meaningless online discussions, long and meaningless online discussions lead to suffering.

If the topic was "a game you don't want DRM-free," then yeah, everything should be DRM-free, including even the terrible games. Showing up on GOG, though? They already curate (maybe even too much), so we already know that not everything will show up. They also provide support, and support being tied up helping someone with a terrible game means less support for those having problems with good games. Didn't they disappear off the face of the planet around the Witcher 3 release for that reason? Maybe I'm remembering things wrong.

(The) Suffering wasn't a bad game though...

I did read the thread.

I don't want ANY OF THEIR POORLY CODED, SOURCE STEALING CRAP HERE.

.....have....have you even played those games? Because they're awesome games. Mind going into your problem with the company in detail, because I'm just not getting it?

The Metal Slugs, Double Dragon Trilogy, Raiden Legacy: Shit Android to Windows ports, when the Android ports weren't that good to begin with. Awful audio quality. Lots of stuttering.

The NeoGeo "ports" sold at Humble: Using an emulator that's SIX YEARS old, with a crappy UI pasted on, and no gamepad configuration available.

Irem Arcade Hits: Poorly emulated games, with awful audio, and the promised fixes never arrived.

Raptor: Call of the Shadows 2015 Edition: Another poor emulation job. Abominable audio options.

The only reason they didn't screw up Ishar, Goblins, or Robinson's Requiem: DOSBox and ScummVM. How could they screw up when other people did the heavy lifting for them?

So yes. I don't want them here.

Why does nobody seem to use workplace computers (solely) for work?
I'm always baffled at how often I hear about people doing private stuff there and wanting to have NSFW labels.
Workplace PCs are not for private stuff, it's as easy as that.

PS: HuniePop is a surprisingly well made game and quite clever in some regards.
