Having said that, now that you mention High Fantasy, we'll probably have the same issue with magic. But at least no one can engage an orbital bombardment, or just nuke a section of the world. 

Also works with your Warhammer theme. Heck, I am sure some of us could even use the species from War hammer since they are all designed to be balanced already. For the most part.

Its easier to balance magic than it is to balance out an army's worth of tecnology.

I would love to use Warhammer races but I'm afraid people might find it limiting creativity wise. I think it still could work out though as long as people don't just copy past in the Empire or Bretonnia or something.
