The subculture of “speedrunning,” demonstrating mastery over controls at its highest levels, is mostly inimical to the walking simulator:
Speedrunning---the concept of completing a game as fast as possible---serves little purpose to the audience in walking simulators. Speedrunning shows proficiency of game mechanics, typically of someone who is familiar with the game but does not hold the same value when applied to a walking simulator.
I find this interesting because in the Steam achievements of Gone Home, there is an achievement for completing the game in less than a minute. I wonder why the creator of the game even created that achievement… Was it to foster a similar experience to an adventure game? Was it a joke, making fun of the modern speedrunning? Was the achievement created at first release, or was it added after player feedback?
