For me it was my first play through of persona 5 in high school. Had heard about the game from my friends and wasn’t sure if I’d like it since I never really played rpgs. But it was 20 bucks on sale and I decided to pick it up and then didn’t put it down for the next month. I had never played a game with so many characters I gave a shit about and story that I could actually relate with. Plus the gameplay was something that just clicked so well with me, the social sim plus dungeon crawling was just the right ratio to never make me bored. And the last section took me about 6 hours total to complete and get to the credits and by god I had never felt so complete in finishing something. I never really reflected on my experiences with a game before that, but playing persona 5 made me realize that I can like a multitude of games that I wouldn’t think I’d enjoy. Thats not even mentioning the visuals and music which I'm sure you know how fantastic they are and that still influence my tastes to this day. All this to say that persona 5 means a lot to me, it got me into the franchise and I’ve played pretty much every other game in the series and even a bit of smt. Its a play through that changed me as a person and I'll always love it for that.
