I'm generally a humanity fuck yeah kind of player, so the orc thing doesn't really appeal to me. I can emphasize the facets I pointed out in my edit of the above post, and see about doing some other stuff. I don't see the similarities that much beyond very broad generalizations (Kind of like how the Wheel of Time and Lord of the Rings could be called the same story if you just hit the major bullets). I think in writing, the differences will be even more pronounced.
