Your logic is flawed. That is the point. It is also clearly why you avoided answering my question. Don't worry though, I will answer yours.
This isn't really debatable, because the structure of how stories are grouped is age old. Anthologies, series, serials, etc. The structures are defined and easy to understand. It is no different if it is classic mythology, or micro-series on Youtube. Star Wars is again a perfect example, as the original film structure was based around individual titles of films, that would still be grouped together in a series. But as the structure of the series and movies changed, it gave birth to the episode numbers, and now the subtitles have returned to prominence, above the episode titles. And even then, the main series will always be divided up. OT, Prequels, ST.
There is also no reason to consider any Mass Effect game without a number title to be a spinoff. Inquisition a spin off of Origins? No. It is simply the next game in the series. Say for example the next game is labelled "Mass Effect: Not Shepard's Story". This structure gives them options to go back and say make Mass Effect 4, something involving Shepard. It allows them to make "Mass Effect: Not Shepard's Story 2". And finally, if that story is finished up in one game, they can start a whole new story in the next game.
To you it is flawed, to me there's no need to give the next ME game a subtitle for being under the ideal that it would be a disservice to shepard giving it a number.
I didn't avoid your question. Once again, I saw the point you were making, and I simply disagree! All famous franchises work differently. One can't always be used as a perfect example to explain the works/mechanics of another. I appreciate you giving a brief explanation of star wars but it doesn't change anything. Not here, anyway.
some franchises, like for instance the one you mentioned, dragon age, also made by bioware, never had numbers in the title, iirc. ME always did. so again, here it's not the same. However, usually at this point in time (after a trilogy I suppose) when a franchise releases a title without a numerical title, the upcoming installment
is seen as a spinoff, or a prequel, or just a derivative game of sorts. That much is true here, or the latter is at least since shepard won't be a part of it.
But what's not true (what I don't agree with you/bioware) is that still giving it the name Me4 is not a disservice to the protagonist of the first 3 games. They can do it if they want or not, either way nothing is wrong the naming; it is after all the fourth mass effect game, they can very well name it that and it wouldn't be inappropriate, period. I already said before that I'd appreciate if they do something like mass effect: subtitle, mass effect: same subtitle 2, and then 3 etc. Again, giving each and every new game from here on out makes it seem like whatever protagonist they intend to have stick around of less vitality than shepard had to his games.
Why would I buy anything from Bioware? I am the one dubious about their output since Mass Effect and Origins. I have no reason to defend them. What bothers me is claiming what they are doing is stupid and illogical, as if it makes no sense. That is clearly wrong. Could they label the next Mass Effect game, Mass Effect 4? Yes. But if they don't, there is a clear and well obvious logic to it.
The Mass Effect Trilogy is Shepard's story. They sold it that way and that is the way it played out. It is so clear why they probably don't want "Mass Effect 4". Because it implies something that isn't going to happen.
To you, it is wrong to disagree with them, calling them stupid & illogical (not sure if I even used those exact words!). But that doesn't mean only you (or even bioware) have the right answer here. I'm not saying you have to be wrong about all this, I'm saying you can't convince me I'm wrong for going against agreeing with what bioware stated about their Me4 naming. And once more, others here have stated it wouldn't be a big deal to them for bioware to name it Me4 as well, with a story away from shepard's. and i'm sure there are tons of others who wouldn't mind it either. it's not an isolated thought.
If your last two statements were true, all they'd have to do is say the new game is Me4 and also state "shepard is not a part of this." They wouldn't be breaking any rules or laws by doing that, perhaps a few hearts though. But how many more hearts can they break after Me3's ending? Most have moved on I'd presume at this point.
