I don't play any gacha so I don't know if there's some marked difference between these two games
but why do official alternate costume posts for Pokemon Masters Ex only have the Masters EX copyright tag and not also the original game copyright tag where the character comes from? e.g. Irida (special costume) (pokemon) posts and how they don't have Pokemon Legends: Arceus tagged
Fire Emblem Heroes alts on the other hand seem to nearly always have the character's original game tagged in addition to the FEH copyright tag. e.g. Ike (brave_mercenary) (fire_emblem) nearly always has both the Fire Emblem: Path of Radiance tag and the Fire Emblem Heroes tag. same goes for pretty much any FEH alt I see.
are one of these wrong? does that one need a (metric ton) of gardening/fixing if so?
if you ask me I prefer how FE posters do it. if people searching for a character (or searching through a game tag e.g. Fire Emblem Awakening) doesn't want to see a FEH alt they can just minus Fire Emblem Heroes from the search. this system also makes fire_emblem_heroes copytags:2 (i.e. only Fire emblem heroes and the master fire emblem tags) a good search if someone only wants to see FEH original characters (e.g. the characters that only appear in FEH and not the mainline FE games).
again I don't play these games so there might be something I'm missing. also not sure how other gacha games for other anthology franchises do it, and if FEH is really the odd one out
Edit: wording / clarity
