Fallout

I'll always fondly love the simple poetry of the Courier's introductory scene, especially in the context of the two games it's sandwiched between.

Fallout 3's tutorial takes the protagonist through an underground infancy, childhood, and young adulthood before opening the vault door to the game's world.

Fallout 4 sees the Player through the apocalypse itself before waking up in a tube and beginning the actual gameplay.

But New Vegas? Just a poor soul dragged from a literal shallow grave and patched up just enough to not die.
