Sure, the first never got much love, and it certainly had problems, but I still liked it - so I'm happy as a clam to see a sequel. I just hope that the development team actually learned something from the first game, and fixed some of their mistakes. (Questionable control, characters who need to drink water every five minutes or they die from dehydration, feeling the need to dumb down the storyline into typical videogame fare in the last 1/4th of the game, etc.)
According to the Magic Box, the second game "takes place in an underground city in the winter time of year 2010, where the torrential rain and mass water flowed into the city." I'm not quite sure how it is raining in an underground city, and some of the shots have skylines in them, but whatever the case is, this time the disaster is water instead of earthquake. The game features two major characters, a guy and a girl, and gameplay is traded off between the two character's storylines.
Game is set for release on Feb. 21st in Japan. I'm not sure how the first one did sales wise over here, so it is anybody's guess if this will come our way.
