Button Mash has, sadly, died, while protecting the - then powerless - Princesses from an unknown force by distracting it until help could arrive.
As soon as he closes his eyes, he opens them, only to see a multitude of words floating before him. A menu screen, saying Game Over, along with some options.
And he then relives his life as a new pony, as a Gamer. His Life is a Game.
Gamer! Button Mash, Anthro! Equestria, pairing unknown for now, and more to be added.
