Now after having done some research, I find myself somewhat disappointed in what I've found. My major gripe is that 200 year war that's affected everything. It really feels limiting to me in the sense that every potential protagonist/npc/player-character will have to account for what they were doing during the war period and there's no way to get around it. If there's a 300 year old elf, he would have live through the war. If there's a 100 year old dwarf, he'll have to explain what it was like growing up during the war. If you have 20 year old human, he'll probably be an orphan. The war will probably be mentioned in every book.
I'm also disappointed that WotC is also pushing this whole 'war ravaged land' idea. I saw the open-call for writers on their website for Eberron. While reading over what they were looking for, they really put the point across that the characters authors write about should have been deeply affected by the war(no home/family to go back to, etc). This seems to be the opposite of the Forgotten Realms philosophy where a character can be as open-ended(within the limits of the ruleset

) as you want him to be.
I've also noticed that Eberron's setting is described as 'dark fantasy'. While I'm not exactly sure what's meant by that, I'm beginning to draw the conclusion that 'dark' means 'depressing' because basically every character is going to have some sob war story. "My brother was killed.", "My home town is in ruins.", "I lost everything and have nothing left to live for.". While I'm sure these characters will find their purpose in life again, probably over the course of several novels and much monster slaying, it's all still very depressing.
