I can't guarantee quality, but it's certainly supposed to be original. Think less FFH and more Glorantha, though even Glorantha is just a distinct inspiration by this point.
As for the playerbase, well, we'll just see. I'm more concerned about kicking it off the ground, but both will have their own difficulties in this regard. I do want to polish the fantasy project some more first, while with 1000 BC I'd just need to re-read the material I've gathered and make up my mind about the rules. I'll do it when I have a bit less stuff on my plate.
