Drawing on existing game design has nothing to do with my point. Nothing innovative comes out of nowhere. Yes, you can trace back its design, but it is a new thing.
Can also be said that the assertion that you can trace elements to some earlier game is pretty dismissive of the overall experience the new game delivers.
There is no other, released game thats really doing what Hollows is in the way that it does it. That some elements might be similar to something else doesn't detract from that nor make it any less innovative.
Its often said by non-creatives that creativity and originality are dead and everything is just derivative. That isn't really true, of course, but it also neglects the idea that performance is something that can never truly be derivative without plagiarism.
Whether you're making a painting, writing a book, or designing a game, your end result is going to be irrevocably unique, even if the style and ideas you utilized are similar to someone elses.
This is after all what makes seeing different takes on the same Play valuable. You haven't seen everything the Play can offer if you've only seen one performance.
Likewise for painting the same scene or object, or reading 5 different books in the same genre.
Lord of the Rings might have been foundational to modern fantasy, but that doesn't make the Ranger's Apprentice, Harry Potter, or Imaro merely derivatives unworthy of the distinction of being innovative.
