> No, you can't do it because the seller of the game does not allow you to do it.
What are you talking about? The game doesn't have the ability to allow or disallow anything. It's just data on an information medium. You can bypass any protections put in place by the developers unless you need to violate the laws of physics in order to do that. Last time I checked, there was no such thing as an uncrackable game.
There is instead a law requiring me not to do that. There are laws, which are enforced by the entity with a monopoly on violence (-- the government). The game developer can only point the government at the people breaking the law. Whichever way you look at it, the government is still involved. ANYTHING related to property has the government involved. Because the concept of property is something guaranteed by.. you guessed it.. the government.
