Rhapsody: A Musical Adventure is not a bad game, but when compared to the original, this remake for the Nintendo DS pales in comparison. Gone is the completely unique battle engine that made the game stand out, and the choice of using the monotone emotionless Japanese vocals instead of the almost universally preferred (even by the Japanese) English dub is bound to alienate the audience NIS America claimed it was gearing this game for – the casual mainstream gamer who doesn't want to invest 100+ hours into a Disgaea title.
As such, the game is far disjointed to pull in the cult audience that the original had. Save your money and buy the PSX version off Ebay. It's superior and worth the extra cash.
