I have always liked PotD and HoH. I never really cared about Eureka or Ballzja but did them anyways. PotD and HoH is reminiscent to the times that I would play older RPGs including Star Ocean and go beyond the final boss, to truly challenge myself.

Personally I'm not sure what I would love to see in a new dungeon but could easily see how a dungeon of "creations" magick would come into play. What are your thoughts the next "infinite dungeon" will be like / what you would like to see? Of course this is assuming there will be one but let's assume there will be for the sake of discussion.
