Interesting. I've honestly never played Dwarf Fortress, but have played Minecraft. However, while the exact mechanics of Ymaggion dwarves as a race are fully new, their cities as they are (Acera especially) were created mostly way back in 2006. Admittably, it took a little while before I made it a dwarven city, rather than a human one, but that was at least pre-2008 still.

I presume that you are a fan of both games though, and thus do not see the comparison as a negative trait.
