Switzerland. There are only two things that I like about it so far: warforged as a playable race, and the art (which is, from what I have seen, sadly, far superior to current FR art).
I am all over this like a fat kid on a twinkie. Looks good, smells good and it is a ground floor thing where I won't feel like I am missing out but is still DnD which is what turned me off of stuff like Dawnforge, Morningstar and Midnight. I want to play DnD, not some wonky variation. I also like action points...
I'm gonna give a look when it hits the sheeves at the local hobby shop. From what I have seen on the WotC site and Dragon, Eberron will most likely be added to my collection. The Shifter race is of special interest to me...
For some reason Eberron is more like Ever-yawn to me. From what I've seen its ok, but just ok. I feel no compelling reason to jettison my homebrew campaign for it. I'll keep an open mind and peruse the material as it comes out. Maybe it will hook me in after all.
Kudos however to the whole "lets let the fan community design the next game setting" contest. That was a stroke of genius.
