Final Fantasy XV Universe is a Thing

[Sephiroth]

Don't get me wrong, I liked Carbuncle and enjoyed the demo when I played it. However, "Ooh, imagine Noctis was a kid and got shrunk in a room full of giant toys!" was just a fun little taster for the real thing and not something that adds any sort of value to the Universe.

It has a much value as a lot of other things in the main title that barely has a story part. It is a dream of Noctis with him remembering what his father told him. I imagine that is more than the fishing thing or others. Other than FFVII where really every single thing adds to the story/overall world lore/story catalogue if you want to call it that (CC, BC, VII, AC, DoC with only LO being a re-interpretation), including novellas (OtWtaS, LT:TKaa, even MwttP), same for XIII which also has novellas like Episode Zero and the Fragment one after XIII as well as the short thing about Lightning after XIII-3. Another good example is KH.
