Final Fantasy 13, and that many people on board made its development complicated, director Motomu Toriyama told Gamasutra.
"With a large-scale development team, we didn't use our time well," Toriyama said. "How do you communicate to everyone in the department what the drive of the game is?"
Toriyama and his team tried to keep the game as secret as possible within the massive workforce, which led to playtesting happening "way too late in the process," he said. Square intended to fix those issues with Final Fantasy 13-2, and implemented production-based milestones as opposed to story-based ones it used at the beginning of FF13's development. Still, more needs to change.
"We are also thinking that we will not do large-scale internal development any longer," Toriyama said. "We have a lot of great creators in Square Enix, but for larger-scale development we will be doing more distributed and outsourced development to reach our targets on time."
