@DavidF:
It is theoretically possible to buy a single disk that you boot a PC from and which runs a game, but the enormous number of hardware possibilities prevents that from happening. You *can* do such a thing on consoles, because the hardware is known and fixed.
I do not expect to be able to boot floppy or CD based games on AmigaOne or Pegasos hardware, for the same reason that you can't on PCs - hardware drivers for zillions of cards.
