The game is not formatted for the PSP at all. It lags immensely on every single battle action in the entire game, in a kind of game that is nothing but a huge series of battle actions, it's blurry as hell, and not even reformatted to take advantage of the PSP's nice screen and accompanying aspect ratio. Play the Disgaea port, and it will become very obvious to you just how terrible The War of the Lions is. As I said, there is absolutely no excuse.
