It's a kids game... well... retro gamer kids during 80s 90s are monsters. We compete as to who can finish games faster and no/less deaths and no save state, sometimes we even handicap ourselves to make the game even more challenging. Now a lot of us are but empty shells of our former self though some have improved to become gods. Which is why it's kind of fun and endearing watching these girls take the challenge of the past.
