mixing sci-fi and fantasy,
Personally, I wouldn't call "Steampunk" as "Sci-Fi".
It's an own genre, as far as I know.
I'm hoping Dragon Commander allows us to fight in human form and if not, then it should allow us to land in dragon form and fight with tooth and claw, I can imagine the fun already!
Personally, I do hope that this won't happen - because it simply wouldn't be fun wading through the masses.
A Dragon is big and very powerful - this wouldn't be much fun, at least not in my imagination. There just would be no tactical gameplay in wading through the masses.
Close combat against other Dragons - now that would be something different, imho ...
