Most companies are more than happy to sell limited edition collectors editions of games to diehard fans that are comfortable shelling out a couple extra dollars for important games, but not Atlus. As with their previous Persona game Atlus is including, for free, pack-ins for every copy of Persona 4. Each game will come with a soundtrack with music featured in the game, along with a pre-order bonus of a collectable art book. Most companies would see fit to charge extra for all of the premium content included, but Atlus is letting it all go for a reasonable 40 dollars.
Persona 4 is the follow-up to the critically acclaimed Persona 3 that was released late last year and was revered as many critics choice for RPG of the year. While chances are very slim that Persona 4 ties into the previous Persona games it seems very likely that they are keeping well within the feel of the series, much the same way that Final Fantasy does.
