If you finished Innocent Sin, you owe it to yourself to play this game. I played the PSP version of Innocent Sin and the PS1 version of Eternal punishment, and I have to say, Eternal Punishment was a significantly better experience overall for me. The combat in this game is actually pretty good, I don't know why it was changed for the PSP release of Innocent Sin because it's way better in the original PS1 version. The story and characters are still just as great as Innocent Sin's but all the mechanics still feel the same aside from the combat system. I found the game to have good amount of difficulty without requiring grinding, but the joker boss fights can get really annoying with a really obnoxious move called old maid. I have one major problem with this game which is that there are a few enemies in the game that can cast a spell that halves your money, I've lost 3/4 of my money in a single random encounter which is absurd, it just leads me to savescumming and negotiating to not lose all my money in case I mess up. I also want to talk about how much I love this game's throwbacks to the first Persona, they're all done really well. It's very similar to its predecessor, but I think it's better almost across the board and it's super satisfying to see the end of the story.
