How long must a game so you can buy it?

[tastyshovelware]

depends on the quality and the price.

TMNT: turtles in time (snes)= 25 minutes to beat. one of the greatest games ever made. $10= good value.

cannon spike (dc)= 30 minutes to beat. another very fun mulitplayer title that's hard to find. $20= good value.

etc.
