Glad you enjoyed it! As many others have already said, you should play Persona 4 now. Personally, it's one of my favorite games ever. If you have a Vita, Persona 4 Golden also has some extra stuff, like more social links and new Personas.
You can also have full control of your party members in Persona 4... I hate having to rely on the AI.
