Final Fantasy XI, the first Final Fantasy MMO, is actually the most profitable game in the whole FF franchise, Square Enix revealed this weekend. It's been over a decade since FFXI launched, and since then, the community has accumulated over 200,000 years in play time.
During the Vana Fest 2012 event, Square Enix CEO Yoichi Wada announced, "Looking at profitability, it's the top of all past FF games."
That pretty much explains why SqEnix is releasing an expansion content for this 10-year-old MMO, Seekers of Adoulin, even while the company is still trying to clean up the Final Fantasy XIV mess.
Interestingly, SqEnix also announced that long-time producer Hiromichi Tanaka would be leaving the company. Tanaka, who signed on with Square back in 1983, when they were an entirely different company. Over the years, he worked on Final Fantasy I through III, Xenogears, and Chrono Cross. Later, he was the producer for Final Fantasy XIV before moving to Final Fantasy XI in December 2010.
Not surprisingly, SqEnix attributes Tanaka's departure to heath concerns, though Tanake did express an interest in developing indie titles.
