One of the more interesting exhibits from Ironmace is its comparison of P3 class concepts to those from Dark and Darker. Nexon claims that Dark and Darker's character classes derive from copyrighted concept art, while P3 and Dark and Darker share an as-of-yet unnamed lead concept artist. 

The artist in question outlines various reference images they used in creating Dark and Darker's characters, before contrasting them with counterparts from P3. 

The artist seems to be arguing that both sets of characters merely draw from the same well of generic, tabletop fantasy inspiration dating back to Dungeons and Dragons, and they all do represent distinct pieces of art rendered in different poses and settings.

Curiously, Ironmace includes a conversation log with ChatGPT where the company attempts to secure a definition of a "PvP dungeon crawl game." While a strange gesture, it seems to be an attempt to undermine Nexon's claim that P3 and Dark and Darker share identical premises. 

Whether that is true or not, videogame genres are not Dark And Darker Gold for sale protected by copyright, and many examples of "Antz vs. Bug's Life" games exist across multiple genres and platforms (Chivalry vs. Mordhau, CoD vs. Battlefield, hell, even Mario vs. Sonic to name a few.)
