Got this at pure random after a friend recommended it to me back when it came out. PS4 version was sold out, so I bought the PS3 version. To say I fell in love with it is a massive understatement. It became my favorite game of all time in any genre, beating out the Zelda series which had been my favorite for over a decade. The characters, music, story, and gameplay all hooked me and never let me go. I was on the edge of my seat constantly, being blown away by the twists and turns at every angle. I had never beaten a game as long as this one before, and despite my final playtime being over 140 hours, I still wanted more.
I snagged a PSP and Vita just so I could play Persona 3 and 4 in their definitive forms (yes, I prefer P3P, don't kill me), then bought a 3DS just for Persona Q (can't wait for the sequel!), and now Persona is my favorite series of all time. Persona 5 literally changed my life, and I know not everyone will like it, but I certainly do.
