They need to make a sequel for The World Ends With You already.
The one thing that looked good in this trailer was some of the different touch screen uses but I haven't played the DS one so I don't know if they're new or not
They really need to make a sequel to the World Ends with You but I'm a little annoyed to see on how the clock-device from the game seems to be implemented in this game, it just feels out of place imo.
