Race is simply what people call different human breeds . That ' s where the problem lies . We cannot just call something with a different term when we want to . Just like there is a genetic difference between a bulldog and a chihuahua , there is a genetic difference between a Scandinavian and an Iranian . Of course , this is totally understandable . A human from Iran was exposed to sun light throughout the centuries and his generation evolved very differently than a human from Norwegian fjords who never saw sunlight for centuries and developed a tougher skin to resist the deadly cold . I don ' t understand how this concludes to these two are different races , though , which is my question . <| sep |> A text based adventure game in which every scene is in a different fantasy language .
