Fidel Castro is not a happy chap. Cuba’s state-run media has launched a fierce attack on a new video game in which the object is to assassinate this leader of one of the last redoubts of Communism before the fall of the Wall. It is not just any old video game. Black Ops raked in $360m in a single day when it was launched in North America and the UK last week. It is the latest in the series of Call of Duty blast’em console games. The last, Modern Warfare 2, was the biggest grossing video game last year; some 22 million units were sold by an industry that now dwarfs Hollywood.
