The EPG does it's job. It provides enough information about the world of Eberron for a player to get a general feel of the setting and enable him to make a character which aligns with the world. How useful the book will largely depend on whether you play in Eberron. Most people who play D&D most likely do not play in Eberron, and neither do nor will I. So just how useful is this book? Well, I guess it's usefulness to non-Eberron players is directly related to the artificer, the PP's and ED's, the new pantheon and the related feats, the 3 new races (2 really, since we already have warforged in eDragon). I must admit that in that regard, the book surprised me. I had only briefly looked at the artificer playtest, as the prior version never caught my interest. But I really like this new artificer. It appears to be a solid and flexible (a great mixture of weapon melee or ranged attacks, magical ranged attacks and summons) class, with lots of potential for roleplaying quirks (lunatic gnome tinkerer anyone?). The Pantheon is really awesome, and it's different from the core and FR pantheons, making it even more interesting. I am not quite sold on the Kalashtar (although it does have some interesting mechanics) and the Warforged (I doubt I ever will though), but the changeling is definitely becoming a permanent fixture in my campaign. Last but not least, the PP's are very flavorful and interesting (God I love the chameleon - was that you Ari?), especially those tied to Eberron. But it should be fairly easy to file of the serial numbers and use them in your own campaign. Overall, and even though I really like the swordmage and FR, I think that I will get more mileage out of the EPG than I have gotten out of the FRPG and it is thus a book that I am not afraid to recommend to any DM, whether he plays Eberron or not.
