Kingdom Rush was also a knockoff tho.. These days its very hard to create something with a unique mechanic, since almost everything has allready been done before. Nowadays everything is a knockoff of a knockoff of a sequel to a sequel of a prequel of a knockoff from a knockoff inspired by a knockoff. Almost everything has allready been created back in the 80's.. even Tower Defense games.
I'm not saying Kingdom Rush invented tower defense games. I'm saying this knocked off the specific mechanics that Kingdom Rush used. Literally everything is a knock-off of everything else that came before it if you don't care about specifics.
