Busy as Kojima’s schedule was during his trip to London, he still took some time to talk about Metal Gear Solid V: Ground Zeroes on Twitter. On March 11:
Since GZ has freedom to enjoy real stealth simulator game instead of linear game, gives high replay value and the play style differs depending on the player. So it fits well on “SHARE BUTTON” feature. But premature release proved that wasn’t my intention.
Kojima expressed his satisfaction about Sony’s new console, and about the DualShock 4, since it happened to be the perfect fit for the ideas implemented in Ground Zeroes. The new ‘Share Button’ goes well with the social aspects of the game.
On March 12, he talked a bit about Peace Walker:
Unlike other MGS, & since it was handheld, scattered segments of story was placed in missions of PW, letting player actively obtained.
I presume many people would get surprised reading the novelized book, as PW is a noble & heavy story where Big Boss settles with The Boss.
Unfortunately, the Peace Walker novel has only been announced for Japan, where it can be bought as a separate item or obtained as a more luxurious edition by buying the Metal Gear Solid V: Ground Zeroes Premium Package.
