A:Answer The other answer is incorrect. All game pre-orders include the digital artbook, digital soundtrack, and behind-the-scenes footage. The Switch version on Best Buy will include a steelbook, either version at Gamestop will include a Joker pin (but don't hold your breath... My friend pre-ordered Persona 5 Royal from there to get the pin and never received it), and the Digital Deluxe version on the PSN, Nintendo eShop, and Steam also include the All-Out Attack Pack (DLC), Persona Legacy BGM (including music from previous games in the franchise), as well as a four-day early access pass to play before anyone who purchased a physical copy.
Hope this helps!
