Disgaea 3 certainly doesn't look "next-gen" at first glance. However, Nippon Ichi swears that this title simply wouldn't be possible on any other platform. Marketing coordinator Jack Niida, commented about the game's sprites, and the complexities they feature:
"It's simply because PS2 lacks the processing power and memory capacity to support Disgaea 3," Jack told Joystiq. "PS2 could not load the same amount of data on to memory and process it like the PS3; therefore, we decided to develop it for the next-gen platform." He added that "the character sprites for Disgaea 3 take 3~4 times the amount of labor to create compared to Disgaea 2," and the team is "doing our best to improve the sprites."
