Games remain one of the best entertainment values in terms of cost per hour, even though there's a lot of complaining about the cost of the $60 game. Even counting those games you purchase and quit after 2 hours, the average vs. movies, pro sports, or even bowling makes video games the best value around.
Many in the industry characterize the game-type battle as one of cost (retail "AAA" box vs. casual/downloadable), but I think it's actually a battle of "epic 15-hour adventure" vs. "30-second game-bite" experience.
Gamers are costing themselves the epic experience of big-budget games by not recognizing the incredible value for the entertainment dollar. I hope we all like little game-bite Ipad experiences.
