But I guess I'll go in order.
1: We've run into the issue of game mechanics with this verse a lot, and it always seems to be a resounding, one-sided 'x thing in game/lore is just game mechanics.'
A great example would be a literal place within the verse:
The Scarescraper. It is a real building in the world, established in Luigi's Mansion: Dark Moon. It even returns in 3; the same place. It is introduced and explained with dialogue from one character to another, and given context within the series lore. By all accounts, and according to the guidelines, it is a deliberate developer choice that is not contingent on game mechanics:
"Mario getting hurt by a Goomba in Super Mario 64
is game mechanics, because taking damage from enemies is just a universal mechanic of the game. Bowser being defeated by being thrown into bombs at the end of the game, however,
is something that the developers deliberately chose to add to the boss battles in which he is fought, as the sole means of defeating him- it's not the result of the game's universal rules, it's a specific event scripted by the development team, and therefore as canonical as any statement or cutscene. Since this is an argument that I often see misused, I would advise people to read (or re-read) the page before using it."
Again, this is a specific place the
developers deliberately chose to add, deliberately choosing the expert on ghosts, E. Gadd, to explain it to someone who would be entering it, Luigi, in game as dialogue and lore. Yet this
building was written off as a 'game mechanic,' simply because it was the building where game modes took place in. Even in the example provided, a boss fight's
location and
success condition within said location is considered specific enough to be canon.
So then, why is a boss room fine to be considered canon, but an
entire building in the series that was a
deliberate developer choice is soley, and only a 'game mechanic?'
