There’s no question that, done right, ‘freemium’ works. Candy Crush’s manufacturer is King, a UK-based company with a David-and-Goliath story; in April, it dethroned the once-mighty Zynga as the world’s biggest manufacturer of pick-up games. The casual gaming companies that make it big have more often been scrappy startups than corporate behemoths. King’s ‘games guru’ Tommy Palm, for instance, is regarded as highly unusual in that he wears suits. He was voted ‘Best Dressed Man in Videogames 2012’, a distinction up there with ‘Best Pole Vaulter in the Old Folks’ Home’. One really big game — for Zynga it was Farmville; for Rovio it was Angry Birds — can be the making of these companies; although, of course, their waning can be the breaking of them. On the back of Angry Birds, Rovio, which was started by three students in 2003, went on to become a huge player in the market.
