"DYRL is an in-universe movie"
Yes, every single Macross anime is an in-universe TV-series or movie, not just DYRL. I can't believe that over 40 years later people still talk about the TV series being "more true" or the other way around.
Where was DYRL depicted as an in-universe movie? Macross 7. What does Kawamori have to say about Macross 7? Well, here is a quote from an interview from the 90s:
Interviewer: "So Macross 7 is also a TV series broadcast within the Macross timeline?"
Kawamori: "Thats right, thats the interpretation. Its not just the movie, they are ALL works of fiction."
I get that one may want to ignore the "word of god", and people that never read any interviews could potentially get that idea from watching Macross 7, but at this point I though it was common knowledge at least across places where Macross fans discuss Macross as to not silently upvote "TV is more true than DYRL"-comments, spreading this misinformation further.
Same applies to Frontier and Delta TV vs movies as well. They punched that message home when in episode 19 of Macross Delta they did the weird franchise recap and featured SDF and DYRL music, as well as Frontier TV and Frontier movie designs right next to each other.
Edit: I don't even know why this whole topic would even be important. Like the differences between TV series and movies aren't that major that it would change anything in the long run, each entry is so far removed from the previous one spacially, and time wise, that those little differences don't matter anyway. It would only become relevant if they were going to make entries that are supposed to link previously existing entries, which I hope that they never do, because that's the space that should be reserved for fanfiction and not official fanfiction. I just read multiple upvoted comments that went "everyone agrees that SDF is what really happened while DYRL's visuals are canon" and I just went "???". Like is it a thing people actually believe, or are people like just going with that take to not confuse new fans or something? I don't get it. I get why people care about canon and maybe don't like the idea of "in-universe fiction". But even then is it so problematic to accept that there are two equally "canon" versions of an event, if we ignore the whole "in-universe fiction"-part of it? I don't get why one has to be "more canon" than the other.
