Another way to consider it is to think of it in terms of entertainment value. The average movie runtime in the US is 114 minutes or 1.9 hours, and the average movie ticket is $11.50. This means I'm paying on average ~$6.05/hr to see a movie. Taking the cost of GTA at $80, then you would only need to play for ~13.2 hours to break even compared to watching movies in the theater. But if I played 100 hours, then I paid $0.80/hr to play the game.
