I've imported the JP version of Persona 5, and it's such an awesome game that I gotta let people know about previous entries, and get them hyped for P5's NA release in Feb. If you don't feel like playing P4G now that you've seen most of it, then you gotta play P3. It's the same as P4, but a more somber game compared to P4's happier atmosphere. Don't worry my child, for I have preordered the Amazon exclusive steelbook double pack.
You don't like games that give you a, pardon my French, mindf*ck? I was gonna recommend games like Danganronpa 1, DR2, DR Ultra Despair Girls, and Steins;Gate, all of which are heavily character and story driven, with some very mind bending twists and revelations. For platformer, Tearaway is heavily underrated, and another underrated strategy/JRPG game would be the Disgaea franchise, maybe even Ray Gigant. I could go on and on when it comes to Vita games.
Haha thanks! Always happy to help a fellow gamer!
