Is this the same Etna?
It's got everything you love about the original Disgaea for PS2 and tons more.
The alternate storyline with Etna is extremely weak. Besides the fact that the voice actor sounds almost like a different person entirely, practically all of her dialogue is with the most annoying characters in the game: The Prinnies and Flonne. Her rivalry with Laharl was what made the game brilliant to begin with, and when they're not paired together and foiling one another, it's really lame and annoying.
The Bottom Line
A turn-based, grid-based strategy game with so much depth that investing 200 hours in playing doesn't seem like enough. Hilarious characters and storyline, addictive gameplay and intuitive controls (unless you're a Final Fantasy Tactics fan, then they're just dissimilar enough to screw with you,) make this game series a MUST BUY on any platform (PS2, PS3, PSP, DS...buy all of them, but start with the original).
