As per tradition, the Vita conversion of the 2011 tactics-RPG features a number of extras, including a brand new "scenario" adventure and more than 50 of the DLC add-ons for the original game. No matter the extras, our review of the original PS3 incarnation suggests fans of the series who've not yet played Disgaea 4 are in for a treat:
"As another worthwhile and entertaining entry in the franchise, Disgaea 4 is still just another Disgaea game. Fans will love it for everything it is, while detractors will ignore it for all that it isn't. This is a game, and series, that isn't out to win over gamers by changing its stripes -- though its fans probably wouldn't have it any other way."
