Square Enix have chimed in with an announcement of their plans to bring Disgaea DS to Euro shores on 3rd April. The DS version of the game already hit America back in September of last year, so if you were being patient then your wait is finally coming to an end.
The game is an almost direct conversion of Disgaea: Hour of Darkness, a game which has appeared on both PS2 and PSP over its lifetime. As such, the game does not boast a huge list of changes from previous versions, but a few DS features have being added to make it worth the money, maybe.
