Currently, the megami_tensei tag is used inconsistently for several posts in the franchise (mostly for Alice who appears in several games). shin_megami_tensei is clearer as all games that have Shin Megami Tensei in their original titles imply it, however there are still several Persona and megami_ibunroku_devil_survivor pics tagged shin_megami_tensei as well.
What should be done here? Should either one of this become a super tag implied by all games in the franchise? From what I understand, the franchise is usually called MegaTen in Japan, while western players prefer the name SMT. In addition, Megami Tensei could also refer to the Digital Devil Story novels which started the franchise. There are 4 pics of it in the site, and they're lost among all the other megami_tensei posts, only reachable by the names of its characters (shirasagi_yumiko and nakajima_akemi).
Related issues: the Devil Children tag is called shin_megami_tensei_devil_children, and implies Shin_megami_tensei, however the Japanese name does not in fact have Shin Megami Tensei in it.
megami_ibunroku_persona is aliased to persona_1, but devil_survivor is aliased to megami_ibunroku_devil_survivor. Clearly one should be inverted for the sake of consistency.
