Following its official re-reveal at E3 2015 in June, Sony's long-in-development adventure game The Last Guardian was nowhere to be seen at the company's Tokyo Game Show briefing in September or at Paris Games Week in October. Now, PlayStation boss Shuhei Yoshida has explained that Sony is purposefully limiting what it shows of the game before launch, in part because The Last Guardian is a story-heavy game.

"Development is going well, but because it's about the story, we don't want to show too much," Yoshida told GameSpot in a new interview. "We wanted to show that it exists, it works, it runs. It's not like we won't show anything before launch, but I think we will try to limit what we show about the game."

The Last Guardian didn't have a place in Sony's TGS 2015 briefing, but the company did build a special interactive version of the game's bird-dog-cat-hybrid creature, Trico. Yoshida said he wished Sony could have brought this unique demonstration to Paris Games Week, but it didn't work out.

After years of speculation, Sony used its E3 2015 briefing to announce that The Last Guardian, which was originally revealed in 2009 as a PS3 title, had shifted to PS4. The game is slated to launch sometime in 2016, though a specific release date has not been announced. It is being developed by Sony Japan Studio and genDESIGN.

Had The Last Guardian stayed a PS3 game, it would have been "compromised," Yoshida said previously.
