because they don't want to play an immersive game that can svck months if not more out of your time, without you realizing it.
they want to turn console on, bash some bottoms see some blood...the end, after one hour they play another game.
PC gamers want to start a game create a character spend 1+ hours choosing appearance, do quests for hours on end, read books, explore, sit back and experiment with alchemy, carefully arrange swords and gems in their in-game house cases, spend hours on the gear looks/choice...etc
BUT console gamers are not BAD, they are just different, its a fact that game companies know since the invention of pakman.
