From Wikipedia <https://en.wikipedia.org/wiki/PC_game https://en.wikipedia.org/wiki/PC_game>: >By 1993, PC games required much more memory than other software, often consuming all of conventional memory, while device drivers could go into upper memory with DOS memory managers. Players found modifying `CONFIG.SYS` and `AUTOEXEC.BAT` files for memory management cumbersome and confusing, and each game needed a different configuration. (The game Les Manley in: Lost in L.A. satirizes this by depicting two beautiful women exhaust the hero in bed, by requesting that he again explain the difference between extended and expanded memory.)
