Isn't the other possibility, though, that the game was just too cheap at $60? And only launch, mind you—I do think another issue here is just how quickly even high-demand games get marked down in price. (This is not entirely in the manufacturer's control—but Nintendo somehow always manages to maintain the prices of their games. Nintendo is doing something smart which no one else is doing...)

I don't know about you, but I like big-budget games! I don't think Bioshock Infinite would have been as good if they had to pair back the art team that constructed that gorgeous floating city, or lowered the amount of experimental iterations which made it possible to get the gameplay feel just right!
