The blu-ray has IP on it that you didn't pay for yet - the little bits showing you the stitches on James Bond's coat or whatever. You can't use the basic DVD to create a blu-ray version.
I can use paper dominion to create zombinion online.
That's the dif to me
Your logic seems inconsistent. If you want to the crispness of Bond's coat, why not say that paper dominion doesn't hold any electronic stuff? I mean, I can use the lower resolution to make the high-res thing to, it's just a lot of time and work.
How can you use the lower res thing to make the high res thing? Do you mean by reshooting the movie? If you want to reshoot the movie, you won't get the exact same production, of course, Pierce Brosnan will never deliver the line the same exact way. But it's fine for you to do that, you're just reusing the blocking, script, screenplay, etc, that you already paid for.
Really? That's fine? So if studio X want to remake huge summer blockbuster Y and release it next summer, that's fine?
If I buy a book, can I type it up word for word, and go get it published, and try to make it as an author?
Studio X violates ethics when they sell Blu Ray version of Y to someone that did not buy the original James Bond film, and does not claim to have done so. When they sell a Blu Ray reshoot of Y to someone who already bought the original film, and thus has already conveyed money to the scriptwriters for the reused script, the scene artists for reused furniture arrangement in scene 3, etc.
Of course if you put up a Zombinion server and let anyone in who gives lip service and says they bought the original dominion, unethical use is going to occur. But I would put the blame on the person lying, because lying is wrong, and if you just ask people whether they bought the game that's an efficient way to put the ethical ball in their court.
There are NES emulation sites that practice this philosophy, they put up copies of old school NES games and, in text on the page, urge you to play only if you own a hardcopy of the actual game. I go to such sites to play games I own dusty copies of for my NES, like Zelda. I do not think it is unethical for me to play games I already own on online emulators.
