"'It's peak,' as they say" - Aigis, probably.
This might sound cheesy, but every time I play a new Persona game I feel like I learn something new about myself. This time around we tackle themes of death, nihilism, the impermanence of everything, and what it means to truly live. Nothing lasts forever, people die and they're gone for good, this is absolute.
I'm at the point in my life now where loved ones dying is starting to become more of a common thing. As goofy as it sounds, stories like P3 help you recenter and contemplate on this concept.
Philosophy aside, the game is pretty solid. I'm a bit torn on how I feel about their faithfulness to the originals, but I think ultimately they made great choices to improve the QoL and overall experience of the game. I say this as someone who never played any original version of P3, but am familiar with that era of Persona via playing P4G. If anything I wish they had been maybe a little less faithful and tried something new.
It's hard for me to say, but I think P3 has my favorite cast....? Regardless, it's very close to P4 in that area. Interacting with Koromaru is definitely more enjoyable than interacting with Teddy or Morgana at least. The other party members also feel more grounded and mature. I'll also cautiously say that I think P3 has some of the best music out of any Persona game overall, especially when it comes to battle music. Sorry P5 fans, the jazz is great and all but I prefer Mass Destruction and It's Going Down Now. Colour Your Night absolutely slaps, Changing Seasons slaps, When the Moon's Reaching Out Stars is bubbly and upbeat to contrast the melancholy and nihilism. And when the music and tone shift in the last month... that whole month was a gut punch.
Pacing at the beginning of the game is a little strange, but in hindsight I understand why it has to be that way for story purposes. I liked the way P4 handled broaching the main subject of the story with all of the mystique surrounding Personas and the world inside of the TV. P3 felt a little weird in contrast because you move to a new school and suddenly everyone's like, "Sup? we fight Shadows in Tartarus during the Dark Hour with our Personas. You start Monday, welcome to the team." It made the first couple areas of Tartarus feel much less impactful than the dungeons and palaces in other Persona games which were obviously specifically tailored around the relevant character.
Even knowing how the game would end, it still wrecked me. Memories of You hits really hard, it's the kind of shit that makes you want to call your mom or some close friends.
Now do this, but with P4G.

Such a blast. The combat is weighty and satisfying. Blowing up bugs with different weapons and gear is made all the more satisfying with the sound design and visuals of guts exploding everywhere. Bugs and bots play completely different too, it almost feels like two separate games. Running through a dark, dense jungle as lasers from the automatons zip all around you makes for some tense, really atmospheric moments. Honestly, as you slowly get better at the game and slowly crank up the difficulty, they manage to maintain this really nice balance of tension and power fantasy. Can't wait to see how updates evolve the game over time. Definitely an Evergreen title that I'll keep coming back to over the years.
