I have been completely bamboozled by my experience playing Persona 4 Golden 5 years ago verses now.
Persona 4 Spoilers:
I originally played Persona 4 about five years after picking it up on steam and did a complete blind playthrough of the game. I did a lot of the normal bits, uncovered Adachi, beat Ameno-sagiri and did Marie's dungeon. I wrap up the game, feeling like I achieved a good ending. The only big problem I had at the time was I felt like Marie's dungeon as a final act was a somewhat anticlimactic note on an otherwise good game. I uninstalled and never touched the persona franchise for 5 years.
Fast forward to now, I got Persona 3 Reload on sale and had an absolute blast. I really liked how Aigis as a character tied all of the themes of the plot into her character development. Looking back at P4 though, I thought to myself "why did Aigis representation as an Aeon arcana worked so well when I felt like Marie also as an Aeon feel like it missed something?" So I go to a wiki to review why she was connected to the fog and why that mattered at all.
From there, everything I thought about the game began to come apart. "Who the hell is Izanami? There's a gas station attendant that did something to you? The game is over and I said my goodbyes, why would I say no and go back to Junes? There's another dungeon?" After finding all of that out, I have never felt so angry and compelled to reinstall a game and play it over something I had missed completely.
Thankfully I had a save just before Valentines day so I quickly got back to March 20th and very angrily solved this case for good this time.
After going through this experience, I don't think I have ever experienced this in a video game before where a somewhat cozy feel good ending is deliberately incomplete. What I wasn't able to explain to myself at the time that I still had some major questions as to they why of it all that I should have pursued yet didn't. Plus, I felt like this was the "good ending" for five years of my life! I'm gonna have some major trust issues with video games going forward after going through that. Safe to say, I'll probably pick up Revival when it comes out because my anger towards that bloody gas station attendant is not yet satiated.
