Just noticed another little thing - praying at the shrine at night, you may sometimes find that somebody left an item there. I got a purifying salt just now. Time to start praying.
On a side note, not only does Persona 4 have a shot of being 2012's highest rated game on metacritic, it has a shot of being one of 2013's most essential RPGs in kswiston's thread here on GAF.
Gamerankings is better for that since they don't have iOS game cluttering things up and you can set a minimum number of reviews.
