“Then I'd like to experience weightlessness.”
In 2026, asked what he wanted to do in space, Kojima said he would like to experience weightlessness. He added that he got motion sick easily and might get space sick too.
“I'd also like to make a game to play in zero gravity. […] So the controls would have to change. […] I'd work out the gameplay and the controls.”
“I could probably make games in space. I want to be the first.”
In 2009 Kojima wrote that if he could have only one wish it would be to go into space before he dies. He said a brief orbit just beyond Earth’s atmosphere would be enough, and that to make it happen he would give up even his position as a game designer, his family, or his own life.
Kojima held that the deeper reason for going to space was not weightlessness, extraterrestrials, danger, or a special experience, but to find out who we are and what our place is. He described the journey to space as a journey to know oneself and the return to Earth as the passage from the past self to the future self; he concluded by asking where he himself would return as a game designer.
On his radio show KOJI10, Kojima described two game ideas he would probably never make: a "forgetting" game in which, if you stop playing for a while, the protagonist gradually forgets information and mechanics — even how to move — to the point that you’d almost have to take a week off to play it; and a life simulator in which the character ages from baby to elderly, with mobility and vision deteriorating, which Kojima joked no one would buy.
