Persona 2: Eternal Punishment is cheap on PSN right now, so I was thinking of picking it up. Then I remembered that it's the second game of the pair of Persona 2 games. Is Innocent Sin required (or highly recommended) to be played first, or what? Innocent Sin is much more expensive, so if it's a Pokemon Red/Blue situation, then I'd obviously just go with Eternal Punishment, but I have no idea what the dynamic between the two is.
Any advice would be appreciated!
