Nothing new with Nexon. I used to play a Mabinogi with my wife many years ago and they had an issue with some players getting access to in-game dev tools or something and spawning high level monsters and stuff in the middle of towns. If I remember right it was something that the original game devs had patched years ago, but Nexus had not bothered to bring in the fix for it.

I’ve never played this one, but I’ve heard a bunch of the music. Some bangers in there.

I did also try Limbus Company for a bit, that seems to continue the same story to some extent (shared world and some returning characters I think). It’s weird ass gacha game though and while it was cool I ended up losing interest after a while.
