HoboXIII: Just seeing Doom 1 and 2 and then Fallout 2 and so on keep coming up as windows 10 it feels a little , ok microsoft stop trying to racket me.
Doom 1 and 2 were recently rereleased by Bethesda, 8th of August in fact, as a brand new version developed from the ground up by Nightdive Studios. It was then natural that the system requirements were upped, but it gets even better, because Doom + Doom II demands at minimum, 8GB of RAM and a beefy GPU. My laptop is less than the minimum but somehow, this release works wonders on it.
You still got access to the DOS versions of the Doom games, anyhow. And by filtering my library to just Windows 7 supported games, you can still play the Enhanced versions of both Doom games, but not the new release.
That said, game devs and even GOG themselves target the OSes with higher adoption for support, this includes basically Win10 and Win11 plus some version of Ubuntu if Linux is supported and I dunno about Mac. At some point, it becomes more of a hassle for all parties to support an old, deprecated OS simultaneously with the current one. You may want to use dev features or libraries that make your life easier but are incompatible with older OSes because they didn't exist then.
I know it's hip to hate on Microsoft, but this is just not it. There's plenty of stuff to hate about Microsoft, but parties other than Microsoft phasing out old operating systems, that's just how this thing works and not some capitalist plot by Satya Nadella.
