Let's get some stuff out of the way:
This ranking only uses pricing games in current rotation, as according to the official Price is Right website. And it doesn't include Contestant's Row, the Wheel, or Showcase Showdown, because while those are awesome, they aren't technically pricing games. The criteria for this ranking included total prize winnings on offer, excitement level, difficulty level, and a bunch of subjective components that I basically applied however I wanted, to tell the truth. So don't look for some ~objective~ truth about consumerism or capitalist society or something. This isn't Marx.
