Why does the act of the creator encrypted their game implicitly revoke the user's right to reverse engineer it? Also does it refer to the encryption or the game.
I'm working on the assumption that the creator, as the creator, possesses all the rights to their own creation. How they distribute these rights is a decision they can make freely.
If the creator chose not to give anyone the finished game, then he has not given anyone the right to play it.
If the creator posts the game on a forum welcoming and encouraging people to play it, then he has given everyone the right to play it.
If the creator gives the game to three of his best friends and tells them not to give the game to anyone else, then those three friends have the right to play the game and no one else. Certainly, the creator cannot *stop* them from giving the game to anyone else, but is this ethically wrong? Yes--they were NOT given the right to distribute the game to anyone else. This analogy extends to resources, as well.
If the creator chose to release his game without encryption and posted it on a public forum welcoming anyone to play with the game or its inner workings or to distribute freely the contents contained therein, then he has given everyone the right to do whatever they wish with the game and its contents.
If the creator does the same as above but states that he would not like the tilesets, which he commissioned and paid for, to be distributed or modified by anyone, then everyone still has the rights to whatever other resources are contained within, but NO ONE but the creator (and perhaps the artist he commissioned it from) has the rights to those tilesets.
However, if the creator of the game chose specifically to encrypt his game, then that is
implicitly reserving the right to the game's unencrypted contents to the creator. The conscious act of protecting the game from decryption is denying ANYONE ELSE the right to decrypt it. Whether or not they proceed to do so is irrelevant; you might argue that decryption is inevitable, but that doesn't change the fact that they do not have the right to do so.
In summary, whether or not decryption can be stopped is a moot point to my argument. The fact remains that if the creator distributes his game, encrypted, then no one has the right to decrypt it and the very act of doing so is a violation of the creator's, the possessor of all rights to the creation, rights.
