Have you heard of Nintendo's Virtual Console service? They've been doing pretty much exactly this since the Wii launched in 2006: old games for the NES, SNES, Genesis, and more for $5-15~. You can't get the Final Fantasy games, because Square Enix probably thinks having the original games would hurt demand for their expensive remakes, but otherwise their selection is pretty good. For PC games, you have Good Old Games, which sells DRM-free versions of classic PC games tweaked for modern hardware (or ran in an emulator, for the really old ones) with no need for CD serials. The future you wanted is already here! What do you know, they even have Myst:

Or you could just Google "no-intro $game_console_of_choice" and get the entire library in minutes that way...
