One button at a time
Twitch Plays Pokemon happened a year and a half ago. Participants all entered individual button presses willy-nilly to get through the entirety of Pokémon. Monkeys on a typewriter, and all that.
Twitch has not been playing Dark Souls for 18 hours. I mean, if one person could beat the entire game with individual voice commands…nah. If it’s your sort of thing, enjoy.
