I for one would prefer something without the classic tolkien/DnD races, and for all that is holy no more cheap racism anologies like DA elves ("Knife-Ears", seriously?). The only time I've seen a good racism-anology was in district 9 and that required a very specific plot + south african context to work as well as it did. If you could just as well write it with humans as with a non-human species (like DA getto-elves easily could have been), don't ****ing do it.
If you are going to do something with racism, I'd rather it be human on human racism (or even better lizard-man on lizard-man) and instead of boring old ghettos I'd rather visit a colony or satrapy suffering imperial oppression from racist administrators (who are racist because they're imperial oppressors, not oppressors because they are racists, ie. I don't want the racism to be the focus, just a nasty little flavour thing). And I'd like there to be a logic as to why they are racist beyond them just being bad/stupid people.
