Thank you for posting bobbipiazza. I came back just now with another addition I wanted to add to my original post, but it seemed a bit late to edit.
Rather than simply asking what guest races we want to see next, I think Inno should ask us what architectural elements we want to see next. Giant towers? Solid blocky buildings? Lots of trees? Lots of crystalline things?
If you told me to sit down and draw Orc related buildings, mushrooms would not factor into my calculations at all. If we get dark elves... when I think dark elves, I think underground splendor and glowing lights. Lots of reds and violets and blacks. Also lots of spiders, because I read Forgotten Realms books like crazy. Is that Inno's idea of what a dark elf is? To me, undead are grey and decrepit, with some purples, lots of bones, and lots of crypt like buildings. With glowy blue lights, because I play World of Warcraft and therefore think undead and glowy blue lights go together wonderfully. I am certain Inno's developers wouldn't agree with me there because I'm coming from a completely different background than them. Inno's idea of what an orc is is obviously not the monoliths I was envisioning when I saw the orcs as an option in the survey. Maybe a better thing to do would be to give us a selection of architecture types, unrelated to guest race names, and fit the guest race to the architecture after we vote for what we want in our cities.
