Depends how much you play. 10 hours pr day and it's incredible cheap. One hour pr week and it's the same as a lot of sports.
The point you bring up is other games. I just complete them. Takes between 4 and 30 hours depending on the game. Never touching them again. You can argue that a game as skyrim has much playtime in it, but to me it was just a game to complete, in 10 hours. People differs, and your point is as subjective as mine is.
Everyone has so much to say
