Sometimes just beating a game doesn't cut it. And sometimes just beating a game faster than anybody else doesn't cut it either. Sometimes, gamers make their own rules and impose challenges on themselves in order to fully prove their skill.
Popularized recently with players challenging the Dark Souls series of games with a wide variety of self-imposed rules and restrictions, the trend of gamers playing (and beating) video games in ways that the creators never imagined possible has hit the mainstream. So the least we can do is pay tribute to the creative, hard-working, and insanely skilled gamers who have beaten games in insanely difficult ways.
