This video essay ‘Monsters, mini-games and Mr Happy’ was originally published in Audiovisual thinking: a journal of academic video, no.2, September 2011. The journal seems to be defunct now, so I’m posting it here. There is a written account in my Gameworlds: virtual media and children’s everyday play (Bloomsbury 2014): 22-26. Link to Open Access book. The question ‘Who is Mr Happy, and why is he so happy, even when he dies?’ remains unanswered, even after all this time.
