the only ways to make these games un-crackable would make them entirely impossible for game owners to do very much with the game without burdensome authentication procedures. Particularly given how vast the industry is, I have a feeling most players are more than willing to say "f'u" and go buy from a different company. And the company's know this. Really, I think the best a game company can do is make their game as appealing on its own as possible, and make authenticated versions as unobtrusive as possible.
