I wouldn't say that they have an innovative system, just that the assemblage is innovative. Creature Collection normally isn't a factor within a base builder, nor is 3D real time boss fights.
Each component has been done elsewhere, but not in this way. I do consider that innovative, because I consider the assembly of unused gameplay elements within a core game play loop to be innovative.
I'm also a huge fan of the FPS/RTS genera for a similar reason.
