Final Fantasy XIV doesn't win "worst Final Fantasy" because it had a bad launch. Though, for clarity's sake, the launch bombed. It was incomplete when Square-Enix declared it ready for market in September 2010 and that showed in its horrible user interface, performance issues, and the bewildering number of inconveniences associated with travel, questing, and trading items. It has improved greatly since those days and the plan laid out by the development team for version 2.0 shows promise.
Despite how quickly Square-Enix apologized for Final Fantasy XIV, restructured the development team, and maintained the free trial period, XIV still represents the worst Final Fantasy
because it betrays how Square-Enix has faltered over the years. Eorzea is a colossal, beautiful world, but all sense of wonder lies crushed under the weight of maddening designs that seem better suited to drive players out than draw them in.
MMOs are long-term investments and perhaps once Square-Enix makes enough changes Final Fantasy XIV may live up to the brand's pedigree. Either way,
Final Fantasy XIV remains a powerful lesson of how even the biggest names in gaming can crash and burn without the proper care.
