I am now done with Persona 4. Having achieved both the normal and true endings, there is no more point to playing again aside from pure enjoyment on my part. ...which I probably will.

Anyways.

There are three endings in Persona 4. There is the Bad Ending (previously mentioned), the Normal Ending, and the True Ending.

Towards the end of the game, the choices the player make obviously affect which ending is reached.

If you avoid the Bad Ending, you may proceed to the Normal Ending.

If make certain choices before the Normal Ending, you may go on to the True ending.

That is all I can really say about the game without spoilers. Speaking of story... I'll have to rate this story a 10/10 in any case. Plenty of great plot twists around, if you don't mind the weirdness.
