Off the top of my head: Moon Tycoon. Only seems to run on Windows XP and hardware from that era. Or at least the CD version of the game.I’ve never encountered a game that was released for a previous version of windows that I haven’t been able to run in compatibility mode on windows 10. And I have a lot of old games, I opened my steam account on the day steam was launched. Which games are you having these issues with?
I do have some games that will not work because it needs Games for Windows live. But that’s not the same thing.
