Oh yeah I forgot about stuff like that, straight up exiting the developed world.
Some games, like Halo 3, developed a subtle rapport with players who poked around the edges like that, hiding easter eggs for them. Certain ones you could only get if you played in ways that made no sense given the circumstances of the game, performed otherwise incongruous actions in order to land on a ledge that happened to lead to a cave, etc.
Halo had hidden skulls in the remotest crannies of the game, and you could pick up the skulls and each one unlocked a new difficulty parameter which you could toggle on to make the game harder.
The elastic corpse glitches are priceless sometimes:
