Playstation 3  Price / Entertainment Ratio  An Essay
by Dave Schumaker (December 7, 2007)
Introduction Let's begin. Cost of Entertainment That's a good baseline to use to begin comparing things. How about the roommates and I going out to a hookah bar (Ziryab in San Francisco!) for a few hours on a nice Sunday afternoon? That's about $20 per person for 2 hours. Interestingly enough, that breaks down to about $0.17 per minute as well. How about a random Friday night in the Mission? Let's say about $50 for 3.5 hours or so (which we know is probably a preposterously low estimate and is likely way more than this). That goes up to about $0.24 per minute. No big deal I guess. So we've established a nice baseline for the prices we pay when we go out to enjoy ourselves. We'll go with a nice average and say our price / time ratio works out to ~$0.20 per minute. For fun, we'll name this ratio the "Fun Constant" or Fc. Cost of Playstation 3 The newly acquired 40gb PS3 is $400. That's not factoring in games or anything like that. So to get that down to the magical $0.20 per minute, that means we need to utilize the PS3 for about 2000 minutes, or 33 hours. Nice! Of course, factoring in games complicates matters. By themselves, it isn't bad though. A game is $60 (ridiculous). Which means that we need to play it for 5 hours before we get to our magical price / time ratio. Equations Fc = price / time ratio So let's put this equation together!
Fc = ( [PS3(cost)/PS3(time)] + [Game_N(cost)/Game_N(time)] + [...] + Game_N+1(cost)/Game_N+1(time)] ) / N(total) So let's look at an example using two games: COD4 (game 1) and Uncharted (game 2). Fc = [ (400/600) + (60/420) + (60/180) ] / 2 Fc = $0.38 per minute. Obviously, this means one should keep on playing. ;) Conclusion Dave
