Oooh you guys want me to reveal all my unpopular opinions dont you.
Okay, I will say it. One of the things I wish for most is a P3D remaster. I want them to add Reload songs and give choreographies to the tracks that are just music videos in the game. I want them to do new social link scenes and costumes to unlock. I want new voicelines and interactions. Adding new custom gameplay toggles wouldnt be bad also.
Aside from this I also wouldnt be against a P3 Tactica or Strikers ^^
Or my most wanted spin off of all, an Arena with every Persona character in it. Though the roster might be too big, so if it happens it would probably be a Tag team game (sigh)
For the story, like I have already said, I dont care about canon and what not so I would be perfectly fine with Atlus using the dream excuse again. They would probably lose their memories at the end anyway.
Buuut if you are asking for new spin offs ideas I... really dont know. They basically made a spin off for all the genres I like at this point ^^*
To cut it short, put Makoto in the game and I will be happy regardless :D

Hello :)
No one will agree with me on this, but I couldn't care less about spin offs being canon or not. I dont care about seeing the characters after the game, i dont care about seeing characters aging, especially after how they treated the P3 cast in AU. For me spin offs should just be fun and whimsy, a way to bring something new and refreshing to the table without disrupting what the main games did, without having to justify their existence or purpose. Does PQ have a purpose in the timeline? Do the Dancing games have a reason to exist? They dont. But despite that, they are good games, my favorite spinoffs i would say. Because they are fun.
So I would be perfectly fine with Makoto returning, because him, along with Shinji and Akechi, have the potential to add something. But I would accept it only as a temporary thing or something out of the main timeline because, even though his absence hurts me, especially in P4AU as a FG player, I know that him returning would just make less significant his sacrifice, and it would be unfair for him to get another chance when other dead characters (...so just Shinji, lets be honest Akechi is not dead) dont and will never have the chance to. It would be a disgrace to the themes of P3 and the effort the game puts to make you understand them.

Also, okay, Liz or whatever brings him back, but at this point, would it be worth it? Both in universe and as plot point? What would be the point of him returning now? When all his friends moved on and grew up, what would be his reason to be back at all? People often say to make him a Velvet attendant, but I dont think Atlus can or will ever do that, because it would make him lose his status as "silent protagonist" archetype (which Japan, the main audience, loves) and spoil P3 for new people. It would bring nothing to the story because the P3 (but obviously also the P4 and P5) cast wont be used anymore in the main games. It would be a meaningless sacrifice (ahah, get it? Sacrifice? Because-) of P3 story.

...to make it simple
-Makoto in spinoffs either non canon or as a temporary thing = okay, splendid, terrific, perfection, I NEED HIM.
-Makoto actually being canonically brought back = ugh, bleh, ugly, stupid. It ruins everything. Worst idea ever. Liz's plan should just to bring his soul to the Sea of Souls, not reviving him.

Hi ^^ thank you sm, I love my design as if he was my own son ;_; maybe I will do something else with him later on :)
As for P5, well, the Metaverse rules kinda force him to go along with them, since the way Persona and cognitions work is different from the Dark Hour. Shadow would probably see the evoker as a real gun so I dont think he can use it. So yeah i imagine him to have a new outfit (maybe I should design it... god i have too many ideas but no time for them-)
With the PT Im really influenced by AU fics honestly, so I see him being bestie with Futaba, playing game with her and all that and emphatizing with her in a way, being besties with Ann also because they both have a sweet tooth and go around Tokyo eating desserts, Ryuji reminding him of Junpei, being a bit creeped out by Metaverse Haru but appreciating her kind and quiet side IRL, having deep and philosophical discussions with Yusuke while getting used as a model (Yusuke would feel inspired by his love for humanity me thinks), not really connecting with Makoto but still understanding her (but he would find funny the fact they have the same name), loving petting Morgana both Metaverse and IRL form (he reminds him of the stray cat near the station) and trying to help him with his issues, he would hate Akechi just by guts (almost like a hissing cat lol), and Ren having some trust issues at the start with him (they are both listeners they dont know how to start a conversation lmao) but the Wild Card connection makes them open up with eachother more and more with time <3
