You literally missed the point.
Yes, some gaming studios do use 1.0, 2.0 etc (which I did mention) to signify different stages of development to the public.
The only purpose of that is to give users a readable format.
But the entire discussion is irrelevant considering the fact that there are numerous games on this site that have had a 1.0 and are marked as complete. While others are not marked as complete. Some even start as 1.0. Games that get a "season 2" or whatever are not marked as complete.
Version numbers are irrelevant.
I can't say I'm familiar with cinema and the way Hollywood does things, but I seriously doubt they put version numbers on movies. Would be funny though.
I'm not even sure what your argument here is because it's so incoherent. Are you arguing that they would update your imaginary version number when they simply changed the title? When they "added graphics" etc? Your argument makes no sense.
What you're describing, apart from the rework, of course, is simply bringing something to a new medium. Superman, Spiderman, etc did not get new "version" numbers simply because they were brought from the world of comics to the silver screen or videogames or whatever.
That said, the complete tag has been removed which is good considering there's so much content that's "missing".
