Because The 3rd Birthday is a game with serious fights, director Hajime Tabata decided to raise the difficulty level of the PSP game.
Tabata assures that the action based controls are not difficult though. In fact, they are "extremely simple." He says people who usually play RPGs should have no problems enjoying the game.
With the game’s release date nearing, we should be hearing more about The 3rd Birthday soon. Nomura mentioned a homepage update, final trailer, and commercial for the game are being prepared.
