Digital image and music assets, particularly original works created expressly for use with original digital games, can be ripped in some way, no matter the method of obfuscation used.
So, to the potential rippers and hackers of my to-be-launched game, I send my greetz to ya all and expect you to kowtow to my greatness as a creator of such wonderful art and music that you need so desperately to rip, hack and pass of as your own or to make money from it for yourselves. I pwn you all when you do that.
