First review I've seen, Rob Fahey weighs in at 8/10.
More information.The result is an art style wildly different to other MMOs. The shards are enclosed worlds; when you look up, you see the roof of a stone cavern far overhead, with light streaming through holes in the firmament. Huge slabs of stone, tossed about casually in the Sundering, erupt from the landscape, while shards of glowing crystal provide ghostly illumination for the many forest glades. Combined with the truly lovely environmental art, the unique setting makes for a game that's a joy to explore. Soft edges and diffuse lighting abound, with beautifully composed incidental music and background sound giving the whole game an evocative twilight feel. On occasion, Spellborn tries to wow you with spectacle - the epic home buildings of the High Houses being a perfect example - but it's usually more interested in a delicately woven atmosphere, and it's all the better for it.
