Quit messages

When the player attempts to exit Doom, a humorous quit message is shown, apparently trying to convince the player to stay and play some more. The message is chosen randomly out of a pool of seven, different for each game. The player must then confirm that they want to exit, by pressing 'Y'.

Extras
When the Doom source code was released, the following extra quit messages were found in the source, some containing profanity. A comment presumably left by Bernd Kreimeier speculates that they may have been for Final Doom, however according to John Romero, these are development mode only quit messages that were never to be seen in a real release version.

Trivia

 * The alternate messages can be added to modern source ports using DeHackEd patches. ZDoom, however, makes the process far easier as all one has to do is create a custom Language.enu with  ("dos is much worse"),   ("you like dos better than me") and   ("dimensional shambler waiting") replaced with their alternate variant and load the file as a typical mod.
