Glad that people are interested in the idea
I thought it was pretty cool too. But yeah, balance for this game is going to be huge which is why I wanted to continue to get opinions on this forum. I'm going to try and put together a basic list of which nation gets what based on my own thoughts and what people have said here so far.
As for the Soulstone (or other artifacts) in early game being too powerful: I agree. There is a possibility that I may shy away from handing out the really commonly used insanely powerful artifacts. That - or I may just insure that every nation gets one artifact that they can use to really leverage thier early game.
