Toriyama continues on saying that Square Enix is considering to outsource large-scale projects to other companies that can deliver games on time.
“We are also thinking that we will not do large-scale internal development any longer. 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.”
Toriyama also says that the Japanese team looked at Western game development while developing Final Fantasy XIII-2.
“We decided that we would have a milestone every month, and realized we needed to applied more Western technology and production techniques. We learned this not only from GDC, but also from Eidos.”
