Playscore as a game score (telling you the worth of a game)

[Zekuro]

When you search a game you often want a game what is good and games with high replay potential. What about a value which is telling you how worth it would be buying a game?

The score i am talking about is hours per money. When you can see the average value of this score from every person who installed and played this game, you can see how worth it would be playing this game.

Even good games can have a low score but the most will have a nice score.
Maybe try it out on your own in your Library and compare the score from your games.

It's just an idea, maybe i am totally wrong and you can explain me why.

As some examples i am leaving some playscores as Examples:

Starbound: 4,8 h/€
Bioshock: 0,5 h/€ (was a nice game, but i just played the story once)
Saints Row IV: 1,5 h/€

(i compared the skyrim score from 4 of my friends)
Friend 1: 1,5
Friend 2: 1,5
Friend 3: 10
Friend 4: 66
AVG: 19,75
