Nexon is a massive investment company from doris's blog

The issue comes from the fact that Dark And Darker Gold the production of Dark and Darker happened after Nexon pulled the plug on a similar project under its own umbrella, P3, which was being made by current Ironmace staff. Nexon Announces New Open-World RPG Based On Dungeon & Fighter

South Korean website Yonhap News reported that Nexon filed a legal complaint about the matter of stolen game code back in 2021 and that the agencies in charge requested a "supplementary investigation" of the matter in late 2022. 

This, presumably, is what led the South Korean police to search Ironmace's offices. While the developer claims that nothing was found and that there will be no additional delays in the game's development, Yonhap reports that the police did indeed confiscate materials during the raid.

Since Ironmace staff doesn't seem to have parted ways with Nexon on particularly good terms, only to proceed with the production of a niche title that's reportedly very similar to the publisher's own canceled project, it's not particularly surprising that there'd be accusations of some sort. 

Nexon is a massive investment company that has access to immense financial and legal resources. Whether anything comes of this, of course, will depend on whether the materials confiscated by the police lead to anything concrete.

In the interim, the virally popular Dark and Darker will continue its development unless Nexon can provide proof that Ironmace really did steal proprietary code. It's possible that the whole situation would've blown over had the game not become so popular in such a short span of time, trapping the devs between a rock and Dark And Darker Gold for sale a hard place with their former publisher.
