Synchronizing 100% personality models doesn't sound easy. The problem is that the old outfits and layer wear are modeled to PSO2 Meseta match the older pso2 body. To be able to synchronize it, they would have to recreate from scratch (haha pun) 8 decades of cosmetics. That is not likely to occur. I mean that I'd be willing to drop a certain proportion of those makeup to help keep things intact across variations. As long as there's a steady feed of cool new things to replace it, I do not mind. I constantly rotate out my older appearances anyway. Provided that the character versions translate 1:1 it will still feel like mine.

The example I can think of is that the Dragon Hunter Frontier Z cooperation where I could envision the clothes and weapons could definitely be given a visual upgrade together with everything else but I don't exactly know how the licensing or how the lawful side of the cooperation works where I'd wish it had been as easy as Sega going through and updating the resources but I don't understand about just how much of Capcom is involved in this process.

The same applies to collaborations such as the Final Fantasy XIV cooperation with Odin (which still exists as far as I know) where I do not understand how much of Square Enix is involved that for Sega to be able to upgrade assets . If it was only just Phantasy Star-related items (such as character outfits, cameos from other games, or alternative Sega-related possessions ) I could envision that this probably would have been achieved, or would be done. But from the worldwide variant we don't have the existence of Cougar NX so I do not exactly know if there are other complications regarding Sega's properties that might also contribute not to buy Phantasy Star Online 2 Meseta updating everything they can within reason.
