And if we're being honest, the player options are not what you get a Keith Baker penned Eberron supplement for. It's the setting material that's the real meat of the book. The player options tend to be a bit perfunctory and of uneven quality.Luckily, subclasses, backgrounds, feats, species, and magic items are all things you can add to DDB yourself via homebrew. I've already added a bunch of things from his other 5e Eberron books for my Eberron campaign.
I'm going to wait for the reviews on this, but only so I can decide between getting the PDF and springing for the PoD hard copy like I did Exploring Eberron. The Droaamish frontier is something I've always been interested in.
