Given that we seem to have already seen the main characters at different ages (e.g. Noctis and some girl as children) in various trailers/gameplay, as well as the fact that Tabata likes FF VI personally as well as the reference to WoB/WoR though the World of Wonder trailer, has anyone considered a break in the timeline for XV?
What if Luna is just a younger Stella? Something happens in the middle of the story and 2-3 years pass before the story continues, like the year-long gap before World of Ruin. During these 2-3 years Luna matures, gains strength and confidence, and changes her name to Stella to cement her growth and transformation.
The only odd part about that is all the anecdotal bits about Noctis first meeting Stella at the signing ceremony but maybe that part's been altered?
