Altus has now dropped the price of the following PSP Persona ports: Persona, Persona 2: Innocent Sin and arguably the best deal in the bunch Persona 3 Portable. The titles will now only cost you $4.99 and are playable on both the PSP and the Playstation Vita.
Persona 3: Portable is as enhanced remake of the PS2 Persona 3 game but with added content. The player can now play the game as a female, which alters the game including characters you meet and social links (which are important in this title). In my opinion, Persona 3 Portable is the best version of Persona 3 and its only $5, totally worth it.
