Market research firm DFC Intelligence has issued a new Online Game Market Forecast, which shows online game revenue passed $7 billion in 2007. That figure, which doesn’t include retail sales, is set to reach $19 billion by 2013. Those figures will, of course, depend on whether or not the entire planet gets sucked into a financial hole (wasn’t life much simpler when we temporarily worried about CERN creating a black hole?). But when you take into account that the PC Gaming Alliance estimates there are currently 263 million online PC gamers, you do have to wonder why people continue to say the PC market is dead or dying. From where we are sitting, it seems very much alive and kicking.
