Yeah, I'd like to see some element to make this different than Earth more than different continents. I kinda thought this was going to be like Dawn of Worlds with a ton of weird races, but this direction is fine, too. I guess now I'm picturing something like the world from Game of Thrones. Mostly realistic, but a few weird animals and some magic stuff on the periphery. But I haven't actually seen or read any Game of Thrones so that could be a completely inaccurate description of the setting. Like Pat said, it sounds like we're a ways from adding in any of that stuff.
So again, how do we play this? what are the mechanics?
