No, these problems already exist
In OTHER unrelated series. Yeah, I think FFTA->FFT makes no sense since the games have absolutely nothing in common besides three words in the title. I can't think of why Game->Game implications could be a good idea unless they are real sequels with enough stuff in common. But those are different from Game->Series.
Same way I'd say Persona->Shin_Megami_Tensei or Persona->Digital_Devil_Saga, or Persona->Raidou_Kuzunoha_Vs_the_Soulless_Army would make no sense since the franchises are already kept well separate (Occidental renaming aside) except for the rare image with all the main characters. Megami_Tensei isn't even a good enough blanket tag to begin with since half the games don't even use that name anyway, and most of the ones released in the west just got "Shin Megami Tensei" pasted on during localization to make them seem closer than they actually are (The Persona games in particular).
The idea of a franchise tage is precisely not to have to search for "Persona_1 persona_2 persona_3 persona_4" if I just want to see all the art for the series, same way you shouldn't need to specify the "Final_Fantasy_Tactics -Final_Fantasy_Tactics_Advance".
