That's why GoG introduced the preservation program. So they can continue maintaining that software. But it's a strict list.
How many indie titles on PC aged out of the platform and have no maintainer?
You get what I'm saying? Even the older console titles can still play on the console they were designed for... but PC is so nebulous that both software and hardware can age out of use.
And once again, I must insist, I am not saying PC is a bad platform. I'm saying PC is a moving platform. Having a set target is a good thing for development and playability. We here are all a-okay with workarounds and emulation layers. But sometimes it's a good thing to just have the person sit down and start playing without troubleshooting.
