As some of you have pointed out, these figures are what I would consider 'sly':
$1 = 2 hours
$3 = 5 hours
$7 = 10 hours
$10 = 15 hours
$15 = Unlimited time with the game.
That's business though ... eh? How about:
$1 = 1 hours
$3 = 4 hours
$5 = 10 hours
$8 = 1 day
$15 = One week
I like this better so I'll adjust the OP.
I've adjusted the subscriptions too because they were far too generous:
Subscription (no time limit):
$25 = 1 month for 10 games.
$40 = 3 months for 20 games
$70 = 6 months for 40 games
$100 = 1 year for 50 games
