I'm curious, is there a large number of players that would participate regularly in chocobo racing if they iterated/updated them? How about minion battles? Some stuff makes sense, levequests being updated/improved would be amazing, and the old exploration zones could a 2nd look with how most of the playerbase has moved on from it, but I think it's okay for some content to remain static as it is and just be there for the few people that want to engage with that content.

Besides, it seems like most players are interested only in moving forward with new content and aren't willing to sacrifice the speed at which they receive new content if it means looking at older content.
