Using movie-math theory as an indicator of game value
(this does relate to War Z, I promise)
Entertainment costs money, and time is money... therefore all entertainment can be expressed as an hourly equivalent.
Let me illustrate... renting a move is about $5, and a movie is roughly 2 hours long, therefore a movie-hour is worth $2.50. To obtain movie-hour parity for your typical $15 game it must provide 6 hours of fun (6 x $2.50 = $15).
If you enjoyed War Z for 6 hours, then you obtained Movie-hour equivalency and did ok.
Casual readers of fantasy novels can spend 10 - 20 hours per novel. A used novel might cost you $5, so a novel-hour is worth $0.33.
If you enjoyed War Z for 45 hours, then you obtained Novel-hour equivalency and did quite well!
However, many of you played War Z for only a few minutes before no longer having fun... so what entertainment equivalency did you obtain?
$15 for .25 hours is worth $60 per hour. Therefore if you only played War Z for 15 minutes then you obtained Cheap-Hooker-Hour equivalency. Not sure why you're complaining though, because the end result was the same.... you got ****ed.
