Well, DF is just a copy either if wanna look at it that way.
It's DungeonKeeper and Settlers and I am sure there are 2 more games I could name that did something before DF did it. That's a - excuse my words but - pretty stupid argument from your side.
Besides, if anything then compare it with Minecraft for the looks and DungeonKeeper for the gameplay.
I get the impression you were like "Ah, look, Dwarves... yeah, cheap rip-off". That's of course the proper way to think not like "Oh, look, seems like we as gamers have a new genre on our hands and there is something different coming up." Guess it's not hardcore enough to be cool or - godly entity helps us - fun.
Honestly, I think DF is shit for it's gameplay and graphics.
