Prinny 2 is great fun if you liked the original. I recommend it at this price, especially so you can enjoy the quality and not feel so cheated when you run face first into the bullshit.
Asagi mode is more fun than the main game, even.
I WILL say that on average this one is even more bullshit than the first but the quality is still there. Except for the wrist-wrecking button mashing you have to do for all the combat.
EDIT: If nothing else, the sprite/background work is amazing. Standard quality from the Disgaea guys but still just great stuff. The voice actors are all different and don't quite bring the same manic intensity as they had in the first game, but they're still quite good. Music is also exceptional. Even if you don't think you can hack it, it's still worth it for the sights, sounds, and humor it'll treat you to.
