Unfortunately, your good time will often be tempered by a futzy command interface that doesn't always recognize your stylus input, although you can make a go at it using the directional pad. An overly clunky and confusing equipment menu didn't knock our socks off either.
Even so, with a lengthy campaign, an addictive battle system, and a cooperative multiplayer mode, Luminous Arc is the kind of title that you can lose yourself in. Of course, there's always a chance you'll accidentally smash your stylus through the touch screen when trying to position your players or tapping through endless text. After yet another well-earned victory, though, chances are that most of these problems will be forgiven.
