The original Doom game, released in 1993, is widely regarded as a classic among gamers. It was not just one of the earliest FPS games to bless us with its presence, but it was also a fairly amazing game. In fact, almost every player should give it a go at least once. Fortunately, the game is so ancient that it can run on almost any platform. The game will run on Notepad, as shown by YouTuber Samperson (Sam Chiet). Yes, that Windows note-taking program can now run Doom.
