four_two,
The Myst sequel, Riven, had more than one ending. Depending on what you did, you could either get sucked off to nowhere, or some guy would shoot you with a dart. I found both...
True this isn't quite the same as getting shot in Doom or Quake, but you aren't guaranteed to pass the game either. All you needed to do was load up your last save point and remember not to click on the wrong linking book or not to open the portal to nothingness.
