I’m no gamer either, after 30 years working in IT I don’t see computers as a fun thing, just a means to an end when I want to self publish my writing. My wife is a technophobe and apart from playing zap the wotsit with my son many years ago, the only game I’ve ever spent much time on was the text only Colossal Cave Adventure on the old DEC mini computers.
Having said that I can understand the appeal of something like Age Of Empires in the same way as I understand the success of Game Of Thrones. Such things appeal to something primal and tribal in us. Human nature has not changed much since the beginnings of civilisation.
