Again its in terms of publisher revenues ( btw an Infographic ), otherwise PC gaming was always on top. It has the MUCH MUCH bigger install base, the much much bigger user base (not copies sold) much bigger verity(especially if we count none core games) its much more customizable etc etc... (we are also the more skilled players)
besides, if anyone want the "console expirence" he can plug an xbox controller to the PC, set the game graphics to average, difficulty to easy and there you go.
