Well I wish they would drop a couple races. I still remember when Orcs were a creature, not a race.
We got humans:
Nord - Traditional light skin, blond hair type.
Bretons - Meditrainian or Mid East look
Imperials - Similar to Bretons (maybe they should have made Bretons Asian)
Redguard - Traditional dark skinned, dark hair.
We got elves:
Dunmer - Dark elf (drow)
Altmer - High elf
Bosmer - Wood elf
Orsimer - Honestly, I still wish they were a creature, like goblins.
We got beasts:
Khajiit - Cat man.
Argonian - Lizard man.
I wish they would drop a human race (or make one Asian so there is more variety) and maybe add a new beast race, or nothing.
A few things, one the orsimer aren't savage enough to be considered a creature, there is a huuuuuuge difference between the Drow and the Dunmer in more ways then one and lastly there is believed to have been asian like humans that lived in Akavir.
The Orsimer seel the most "Asian", atleast in Architecture and Armor design.
That is where you are wrong, the orsimer are nowhere near Asian like, closest cultures that have asian influences would be the Akavir and some say that the altmer have kind of a asian architecture example: The Thalmor Embassy.
Well... Do you mean 12th, if going by Skyrim's race system? The Dragons in Skyrim are actually the 11th Race and if you change your race via script on the PC version then you can set your race to '11' which will turn you into a Dragon.
Anyways... Dwemer. They invented Robots! I want them to make a return to Tamriel so they can invent Hand Cannons that shoots Sweetrolls!
(Sweetrolls = Muffins in TES series!)
The dwemer are never coming back to Tamriel, only one Dwemer managed to escape the fate of the disappearence and its unknown if he is still alive since the corprus disease he was infected with means he can live forever.
Now there are other sentient races in TES lore, we know that some goblins can be considered sentient and Orsinium did have ogres and goblins living together with orcs but we don't know how they treated the other races. In my opinion the Igma would be a good race but they never leave Valenwood, there are other forms of sentient lizards in black marsh as well as the hist being considered alive and sentient, thus can be considered a race but neither of those will be playable. The falmer are far too gone to be considered sentient and are far too savage, the ricklings of Solstheim could become more friendly to outsides since the Dunmer started inhabiting Solstheim, but I highly doubt it. An akaviri race but again chances are low as for the Maormer and Sload we have no clue about their relationship to the races of Tamriel besides that the Sload use to buy slaves from the Dres in Morrowind.
Buuuuut anyway I doubt we'll see a new race in the TES universe thats playable without modding or using the console.
