最终幻想XII
"Final Fantasy XII" once held the Guinness World Record for longest development period in a video game production, with a total of five years, spanning from 2001 until its release in 2006. At a "Final Fantasy XII" "postmortem" at MIT in March 2009, Hiroshi Minagawa mentioned that several years of production were devoted to the creation of custom tools used for the development of the game. It was also listed as 8th on the Guinness top 50 games of all time in 2009.
