Undertale is the first truly post-modern video game. This is the bold pronouncement I read in a forum thread as I was considering picking it up, and well...as a pretentious nerd always desperate to lend some intellectual legitimacy to my untold hours sacrificed at the altar of video games, how could I say no? 10 dollars and 8 total hours later and I will go one further: Undertale is one of the most important games to be made in the past decade.
