Is PC gaming dying, changing or growing? Anyone who answered dying, go and stand in the corner. If you answered either changing or growing, have a biscuit and feel proud of yourself. That said, every man and his blogging dog seems to have their own pet theory on the state of PC gaming, and that can make it wildly tricky.

Compounding this is that 'PC gaming' has become an astonishingly broad term. Are MMOs, for instance, a mere part of PC gaming, or do their players' tendency to stick with one game for years now make them a separate industry of their own? Should the independent developers churning out inspired Flash games and mods be lumped in with the mega-budget Need For Speeds and Crysises of this world?
