In terms of originality, I'm talking concepts. Lack of IPs. Let be real, HHN would never do a maze like Mesmer, Trick or Treat, Waxworks, The Depths, Shadowlands, etc.
And even when HHN has ventured into non-IP territory, the look of the mazes still feels very similar to their IP mazes. At Knott's the mazes are for the most part, very distinct from each other.
