It would be great if some of the (newer, newish?) level designs made it into the clockworks. I can think of at least 3 or 4 different arena maps in the game, as well as variations on other level types and special mechanics. It would be neat to play these with varied monster types and status, and at different depths. My argument is this... you can add more random variation to keep some of the veteran players on their toes with a minimal development effort.

I would consider various floors from most missions / events / danger missions that don't have a representation in the arcade now.
