There is a finite patent of prescription drugs so over time they go to their marginal cost. Anyway, I see little advantage to extending copy write on games over 7 years. The idea that you can make money selling copy's of something who's author died 65 years ago seems stupid. Society decided to extended copy write protection to promote people making things, pretending it has value beyond that is silly.

PS: I hereby copy write every number from 1 to (12345 ^ 12345)^ 12345 converted to binary, which covers every software that is ever going to be produced until the end of time. Now pay me money.
