GameSpy reviews Mystery Dungeon: Shiren the Wanderer

Shiren is absolutely and utterly a game for the hardcore. Being flung back to level one for dumb luck or a simple error is infuriating, and Shiren lacks the storytelling polish that many gamers expect from their titles regardless of genre, but the core game is very well done. If all you want is a new hard-boiled dungeon-crawl with no window dressing (or Pokemon), then Shiren is just what you've been waiting for.
