DQX Either has a major content expansion coming as well or just recently had one. Which may be why this event is being rerun now.

I think the last rerun of the FFXI one was on a game anniversary.

I still feel like we should have a PSO2 crossover since we never got one over here during their collab years ago when PSO2 players got FFXIV themed rewards and could randomly find and battle Odin.
