>>26461062>But why do I need that distinctionHere's probably the main reason they even adopted the language to begin with.
Lets say TCP is doing a Pokémon distribution, like the ones' they've been coincidentally doing all year.
If they announce "We'll be distributing Legendary Pokémon.", it means that the Pokémon will be ones that can be caught during normal gameplay.
If the announce "We'll be distributing Mythical Pokémon." it makes it clear with as few words as possible that the Pokémon being distributed can't be obtained through normal gameplay.
If you seriously require further explanation than this, I'm guessing you're either not fast on the uptake, or are just fucking around.
