Your right, the Human, Orc and Elf races are way too overdone. It does look like just another RTS and it could be. I was also hoping for some different looking types too, like human regional groups with a more Japanese or Persian feel to them as well. I always reserve my judgement to when I actually play the game though. None the less its caught my attention.
This game wont be taken seriously until it can prove its truely different from the crowd and that wont come until a playable aspect of the game is released.
