And knowing that I have people who want to play a variety of races, a more metropolitan world seems like it might be better. I've just been reading through my Kalamar stuff, among other things, and while the racial tensions are interesting, the fact that only one or two cities in the whole setting are very mixed in terms of races is rather off-putting.
Sorry for the thread interruption, but I couldn't let this one pass me by.
If you look closely at the cities in the Kingdoms of Kalamar setting, you'll see that there are a lot more mixed race cities. ( I've been working on the City Map Folio lately, so I know whereof I speak even better than usual.

)Granted, the human cities are mostly human, but there's still a good mix.
For example, here's a handful of cities (and most of these are from Kalamar itself, not cosmopolitan Reanaaria Bay!):
Balelido; Population 6,400; Isolated (6,000 Kalamaran humans with Reanaarian, hobgoblin or other humanoid heritage, plus 400 hobgoblins and other humanoids).
Bet Bireli, City of Ears; Population 10,600; Mixed (8,800 mostly Kalamaran humans, 300 dwarven refugees from Karasta, and 1,500 various humanoids).
Bet Dodera, City of the Mounts; Isolated (17,000-17,500 Kalamaran humans; 500-900 elves, half-elves, gnomes and other humanoids).
Bet Rogala; Population 20,900; Mixed (approx. half are Kalamaran, Brandobian and Dejy humans, with other half being even numbers of gnomes, halflings and elves).
Prompeldia, City of Thieves; Population 15,800; Mixed (9,800 mostly Brandobian humans, 2,200 halflings, 800 hobgoblins and 3,000 various humanoids).
Shrogga-pravaaz, City of Giants; Population 5,500; Mixed (mostly even numbers of humans, kobolds, hobgoblins, gnolls and bugbears, with a handful of ogres; even larger creatures sometimes visit).
Shyna-na-Dobyo, City of Celebration, City of Wine; Population 17,510; Mixed (17,000 humans of Dejy and Dejy/Brandobian/Kalamaran heritage, plus 510 dwarves and elves; many halflings live outside the city).
Now back to your regularly scheduled Eberron discussion...
