Yes. There always was a console selling game, and there always will be. More so in this generation than in the previous ones.
Look at the PS3 right now. What games practically sold the console? Tekken 6, FFXIII (In spite of both of them being multiplatform, they still count.), MGS4, Resistance 1 and 2, God of War III, Uncharted, inFamous, Heavy Rain, and Motorstorm.
Keep in mind that these are just examples. But the point I'm trying to demonstrate is that YES, there is such a thing called a console selling game, but they vary differently from person to person and according to tastes. One person will buy a 360 to play saaay... Halo, whereas another person will buy it to play RPG's like Fallout 3 or Oblivion.
So yes. There is a console selling game. It just depends on what you as a person demand and ask for in a game.
