Yeah, though I have a hard time imagining much specific to FFX that would be an easy reference. I suppose they could call some machines machina or the like, but that's kind of wonky.

And Dalamud still works as an FFIV reference honestly, even if it's not as direct as FFIII and the Crystal Tower stuff. I'm not sure what else they could do though. FFI and the Temple of Chaos could be fun. I'll be kind of miffed if all of them don't get their own raids or dungeons though now at this rate, which is kind of a bad precedent.
