Nice sentiments from their financial updates.
-Multiplatform
-More frequent releases
-More unified integration of talent across the company.
They also alluded to FFVII Rebirth canabalising FF16 a little bit and vice versa. I think this is something not a lot of people touched on but it definitely would have helped VIIR to arrive in a more quiet period in the year and would have helped XVI if its DLC did not arrive whilst people are literally still playing Rebirth. Probably a Summer-September release date would have given Rebirth a better sales window and allowed XVI to get a more meaningful boost from its DLC.
In terms of efficiencies, I couldn't help but notice that FFXV (+Forspoken), FFXVI and VII Rebirth all have widley different qualities of world transversal. Ironically, FFXV has a better implementation of the parkour and textual animations then either of the recent FF games. I think this points towards an inefficiency in terms of how they're creating these systems from scratch and not necessarily having a unified platform/engine for growth. UE5 is not perfect but I think it only makes sense now, that they build all their HD games from it going forward.
