This review will mostly cover the added content without trying to spoil it!
This version of Persona 4 fixed all my issues I had with the original, with additional content including new animated cutscenes, new social links, a new story line, new music, a new dungeon, and a great effort of rebalancing the game, This is the definitive way to experience one of the best JRPGs ever released.
Touching upon the new content itself, the new social links are the best and worst thing added. Giving the player time with one of my favorite characters and introducing a new character that is one of my least favorite, regardless of my thoughts on their social links themselves, both add to the story extremely well overall, alongside the added month this works great together.
The new dungeon is horrendous if you don't figure out the trick to understand it which is why I can't give this game a perfect score.
This is definitely still after all this time my favorite game, with nothing coming close to giving me that feeling I get while playing this game.
