I have played every edition of D&D ever published, I love to see the older edition information updated to fit the new model. It is especially enjoyable when so much of the flavor carries through and only the mechanics are altered. Eberron has always been a high magic world and I found the idea of Eberron, problematic for a lower magic edition; to my surprise it is handled very well and offers all the best pieces of the older editions with some nice twists. Overall, I give it a 4; it is still being updated and hopefully the final updates will include some additional information; an Artificer, a few explanations about warforged integrated armor, and Eberron faiths.
