As one of Facebook's most popular app makers, Playfish shows how Facebook can be a gaming platform – and one that's already, in terms of popularity,leaving Sony, Microsoft and Nintendo in its dust. Investors including Atari CEO David Gardner have put a total of $21m (£14.7m) into the company, and with the average player spending 30 minutes with a Playfish game every day, generating between 15 cents and $1 each per month in revenue, its ventures seem astute indeed. We met with CEO Kristian Segerstrale in the company's London studio to talk about the brave new frontier he's been exploring."
