Buying my home was one of the most stressful moments in my life, but in comparison to Final Fantasy 14’s prospective homeowners, I had it easy. There’s a real estate crisis in Eorzea, with too few homes to keep up with demand. And after the 4.1 update, The Legend Returns, things don’t seem to have improved. 

While most MMOs with player housing use instances to ensure that everyone has a chance to snatch up a plot, Final Fantasy servers only contain a specific number of homes, and when one of them is purchased, that’s it taken off the market.
