I love this game. I love it so much. When I first played it several years back this was the only game that ever even came close to making me reconsider whether FF8 was still my favourite game, and I can't overstate how crazy that was at the time. I consider FF8 and P3 to be join-favourites for different reasons, but I guess if I had to order then I'd put this second, though that's not to understate how much I love this game... it's just perfect, it's like it was made for me.
Characters have always been my favourite part of games, and Persona 3 has probably my favourite cast of characters from any game, but P3 also gave you the ability to form personal connections with them via social links and make you feel as though you as the player were forming closer and closer friendships with the characters - I LOVED that, so much. Aigis is my favourite character from anything too. I really prefer the chemistry they had in P3 more than P4 and P5's too, and living together with them in the dorms made you feel closer with them which was nice, I wish 4 and 5 did something like that too. On top of that P3 has an amazing story, and my all-time favourite ending from anything, it makes my eyes feel heavy just thinking about it. At first the music really put me off but it grew on me and now it's one of my favourite game soundtracks, my favourite in the Persona series for sure. I love the dark feel it has too, like it's not overly gritty like the other SMT games tend to be IMO, but it's on just that perfect sweet spot between gritty and vibrant for me. The newer Persona games lean more towards vibrant, and I love their feels too don't get me wrong, but P3 got the feel just perfect for me.
This is getting too long and people are gonna get annoyed at me so imma cut myself off here but I could honestly go on all day, I get so riled up talking about how much I love this game. 10/10 doesn't do it justice. It's just something really special.
