Yes, I have played it and still replaying it. In terms of the game and concept, I like it. Although I liked Persona FES 3 songs and themes better though. Also I enjoyed the Japanese version more than the NA version in terms of the voices. But the extra that came with the NA version was good.
Back to Persona 4, I found it pretty interesting since if you play without the walkthrough, you have to think about how you plan to juggle your relationships with people and get them all connected to you while coping with other tasks as well. No spoilers though so I'll leave it at that.
You better not void quest, because you probably get a bad end. Like HatoriTakaya said, you need a lot of connection to get True End. I get True End at New Game +. You can not get True End at first try.
