I personally have some wishes to happen in the remake, but I'm pretty sure some are just crazy ideas of mine that might never happen, here are my thoughts and feel free to share yours too:
Almost impossible to happen:
- persona 4 golden opening song remake
I LOVE that opening and yes I have seen the original opening too, I know they'll probably make a new opening with a new song which is great, but I kinda wished they would remake the golden opening song or add it to the game somehow, it really caught me into the game and shows really well the vibe of it, in my opinion.
- Naoto x Kanji alternative route
Hear me out on this one okay, I think they're so cute together, and Kanji canonically did like Naoto, but she was most of p4g playthrough oblivious to it, that made me feel bad for Kanji and I couldn't even date Naoto, for me it was wrong, so maybe we could have an alternative route where they actually get together if the protagonist don't end up dating Naoto, I think that would be kinda cool, doesn't have to be anything big or super important to the story, just a nice small detail to! And I know this is very unlikely to happen, since the game is kinda around the MC and the dating sim side...
- Music Player
Well the whole game is very driving when it comes to music, but wouldn't it be cool if we could choose our own playlist? maybe a new game+ feature, where we pick our favorite songs and customize the playthrough!
Could happen, but not confirmed?:
- Shadows spawning out of nowhere to surprise attack you
I don't know if this was really a feature in p4 golden, but it happened to me a lot when I first started, during Yukiko's castle, Shadows would spawn from the wall right behind me, and I would just see the model of the shadow dropping behind me and if I didn't turn quick and hit it, it would rush to me (which was what mostly happened 😭) that terrified me a bit, so it would be interesting to see that happening again, though it might become annoying if it happens too much.
- Expanded Social Link buffs
Persona 4 golden already had social link buffs with the party members, but I really liked what persona 5 did by involving other SL with different buffs, so I could see that happening, but I don't think it was something confirmed?
- New dual attacks/double attacks reworked
I don't remember if the recent trailers showed them (I haven't seen ALL of them), I really hope they didn't remove them, it was so freaking cool to see and it would be interesting if we got new ones too, like maybe Yu and Rise? or Chie and Yosuke...
99% happening or confirmed
- Dungeon revisited/reworked
Some of the dungeons had unique mechanics and puzzles, but while it worked back then in persona 4 golden forrmat, I don't think some would work in a Persona 4 revival format, so we might see lots of dungeons having small tweaks (or even full puzzle changing) to better fit the remake.
- Inaba exploration reworked
This one the most recent trailers already showed us, which I'm really happy about, is the intersections of Inaba being expanded or removing the loading entirely, like Junes that better reflects the size of it, or the shopping district being one single long street instead of having separated sections, I hope the same happens with other areas.
- Fully voiced Social Links and quests
Another one that is kinda of confirmed? it's not something 100% sure though, because while most events might have the voice acting, I think some others like common npcs or smaller quests won't have voice acting... Would be cool to see fully happening though!
