I always say this will be my last Metal Gear, but the games in the series that I've personally designed and produced-Metal Gear on MSX, MG2, MGS1, 2, 3, 4, Peace Walker and now MGSV-are what constitute a single Metal Gear Saga. With MGSV, I'm finally closing the loop on that saga.
This may sound pretentious, but I don't like being thought of as 'the Metal Gear guy.' There's a lot more I can do.
I respect Shigeru Miyamoto, so there will be a lot of mushrooms in Metal Gear Solid 3. But you cannot eat turtles.
