Gog hasn't given the impression lately that they care about old games anymore, honestly it was starting to feel like Zoom Platform (terrible name) cares more.
I do have some grievances about Gog. Offering inferior versions of games (Simcity 2000 for DOS like someone else mentioned, also the CD versions of the Gobliiins trilogy and Loom.) I think Simcity 2000 for Windows does have a 32-bit version, but I'm not sure it even runs on Windows 7. Gobliiins and Loom could be chalked up to licensing.
One other really annoying thing is that Scummvm games usually remove the original executable files, meaning you can't play Scummvm DOS games on an actual DOS PC without pirating. Some other games with replacements for the original executables have this problem as well. There's even been cases where previously-unsupported games have Scummvm added to them,
removing DOS support from games that used to have it!
It would be nice if Gog supplied ISOs of the original discs for crazies like me to be able to play on a retro PC. Then again I often try to get physical copies anyway. I guess it's too niche to bother with, and outside their mission.
Actually, I imagine Gog is missing many early Windows games simply because there's no legal way to make them compatible with modern Windows. There's no wine to make 3.x/9x games work on Windows 10 (well anyway) and Microsoft would never allow them to bundle an actual copy of Windows 95 with the games. DREAMM by Aaron Giles seems to be the closest anyone's got though. It's focused on LucasArts games but he recently
posted on mastodon that it's powering emulation of some old Tetris games in a compilation from Digital Eclipse. Maybe if Gog cares they could license its Windows emulation from him? And many of these old Windows games use Director which Scummvm is working on support for, so that might help, but we'll go back to the problem of missing the original exes... Let's see what happens.
