Since it is on PSP, I did not officially number it. (是中文譯文問題,小島沒有說PSP的MGS就不是正統續作...) But the game design, story, number of staff and budget-you can say that this is a big project. It would’ve been number 5. It’s not a side story or a spin-off. It’s not like Portable Ops or Acid. I am deeply involved and this is the next Metal Gear.
