Luminous Arc review at Gamespot.

"It's not hard to find turn-based strategy games on the Nintendo DS to consume your free time, and Luminous Arc is a nice little entry into that niche. While the game's storytelling is a little on the bland side, it's balanced out by a solid battle system and voice work that's good, for the most part. With 25 story chapters and roughly as many hours of gameplay the first time through, this is an accessible tactical adventure with a number of extras to earn and without a bunch of needless level grinding.""
