>>53791198V was redone and rewritten multiple times as it went though development hell, and Atlus has had a newer younger staff since the development of IV. They really don't know a lot about how SMT works and it's why you get constant nostalgia pandering in IV with references to the SNES games, and retreading Nocturne's ground in V. It's really ironic because Nocturne was meant to be a revisioning of the typical SMT formula and not connected to the timeline
