"I think that in order to prevent other MMOs from catching up, we should flesh out what it means to "live" in the world of FFXIV with things that only FFXIV can do, like Perform and the housing roleplay stuff. "

Um.... Has he SEEN Lord of the Rings Online? While not too popular is has a music system that is pretty amazing. If anyone wants an idea, look on youtube for something called Weatherstock. It's a HUGE musical event that players put on in the game every year. Compared to that Perform is rather simple.
