In my personal opinion as someone who is not a judge and does not claim to speak on behalf of the judges,
It is an entertaining and well-made movie, but the issue is still whether it is complete.
The ruling precedent for this branch is that it does not properly complete the game, and thus it violates the movie rules. The concept of
stare decisis, i.e. respecting a previous decision as correct, exists in any community that follows laws or rules in order to ensure that everyone is treated in a fair and consistent manner over time—unless the previous ruling was a demonstrably erroneous interpretation of the rules.
But I do not believe that the previous ruling was erroneous. The burden is on the author to provide a strong reason for overturning the previous ruling. I do not see enough of an argument. I believe it is true that a "bad ending" of a game can be published if it is an actual completion (there are plenty of examples on the site), but I believe that this movie should more accurately be called a "failed ending."
I feel that it is similar to the
Ghosts 'n Goblins failed ending, in which the player defeats the boss on the final level but cannot access the final boss without having the shield and gets a clear message that there is more to do to reach a completion state.
"This weapon has not effect" = failed to get shield = failed to beat final boss.
"Where is princess?" = failed to get keys = failed to beat final boss.
If I were trying to argue that there is a good reason to overturn the previous ruling, (which I am not,) I would point to these 2 movies:
[3168] NES Gimmick! by Aglar, Hotarubi & Samsara in 04:24.61
[1546] NES Gimmick! "100%" by Aglar & Hotarubi in 07:44.45
The shorter Gimmick movie doesn't beat the real final boss nor save the girl. But, unlike this submission, it has a clear ending—a textbook "bad ending." It goes to cutscenes and credits. Whereas Ghosts 'n Goblins and Extra Super Mario Bros both want the player to continue playing after the failed ending.
One other thing that I think has been overlooked: the author says, "the game states that this is the end," but I don't think that's true, in context. The game initially says "the end," but then an ellipsis (...) appears. An ellipsis used at the end of a statement, when not quoting someone, indicates that the writer is wavering in their belief. The ellipsis signals "wait a minute, something's missing." And so arguably
the game itself is saying that this is a failed ending, i.e., "I guess this is the end... wait, is it really? No, I still have to save the princess." This usage is also in stark contrast to the real ending, which definitively states -- THE END --.
