Tbh this is first time I learned japanese being divided over mods. As stated on the written article, Capcom and Square Enix on Final Fantasy are those that “worried” by mods because they deem some stuff are too “over to the top”.

On Assetto Corsa for example Japanese players embrace modding because it is one of the only way to fully experience driving over real course like The infamous Shuto Expressway network that back in the day used for street racing.

No, however it loosely contain some elements of mainline games like alignment “Law vs Chaos”, multiple endings, and moral/motives. Full body expands the multiple endings a bit especially with the new character.

If someone wondering how big is the Megami Tensei universe (the series as a whole), this picture below probably the closest I can get. There are other pictures too but I guess this one is the one that have connection between the games.

EDIT: I remove the image link just to avoid the headache of the lore and consistencies.

Imo what I like from this series (especially on the main line series) compared to the other JRPG games is that the mythology portrayal, the mature themes and the battle of “Law vs Chaos” is that great and doesn’t shy away from source material. I couldn’t explained it myself but it is just something different than your average JRPG.

Oh and Megami Tensei almost always has banger OST if you all never played them.
