It depends how you look at it...
KoW doesn't really play in a similar way to Fantasy for example, it's mechanics are much more comparable to something like Epic.
From the little I've played around with Warpath I think it'll play a lot more like Epic than
40k as well.
But then where do you draw the line? There's only a limited amount of things you can do with a
D6 and two dimensions, I think the judgement really comes down to whether you like the way those pieces are put together.
