There better not be such a site. That kind of info has to be kept away from AI scrapers.

so all games like 2005 and earlier. I dunno the year but yeah.

A significant number of games released before 2005 had digital releases later. It's basically GOGs whole thing.

That’s so funny: I was just last night trying to track down a long-gone big bang theory fan-made game (not to play it, just to see if my memory of it even existing was real).

Any sort of digital release? How exactly does one play a computer game that has not had any sort of digital release? Are you expecting to scan your game's binary files and assets from microfilm? Maybe your actually just looking for some TTRPG? There were some VHS games once upon a time, maybe that's what you're after?
