"Dragon Sword's excellent graphics and sound, nicely balanced difficulty and satisfying combat system ends up culminating in a great six-hour adventure, more than enough for a portable system. While dedicated gamers can whip through it in a couple nights, more casual players will probably spend a week or two on it. This doesn't sound like much, but when you consider that even quality home console games like Call of Duty 4 and Portal are featuring single-player games that fail to hit the ten-hour mark, Dragon Sword seems perfectly acceptable.
And once the initial adventure is over, players will probably find themselves unable to resist returning for another run through on a higher difficulty level. Because while Dragon Sword is short, sweet and linear, its easily the best game to be released on the DS so far this year, and a must buy for anybody who is even remotely interested in going ninja on a bunch of supernatural thugs (read: everybody)."
