Hideo Kojima recently dropped a bombshell on his radio show, "KOJI10," sharing a wild, experimental game concept: a "forgetting game" that's deeply tied to real-world time. The gist? If you ditch the game for too long, your protagonist will start forgetting crucial info and skills, eventually becoming completely incapacitated.

It's no secret that Hideo Kojima, from "Metal Gear" to "Death Stranding," has always been synonymous with bold, groundbreaking game design.
On the show, he reminisced about using the system clock in "Metal Gear Solid 3: Snake Eater" for mechanics like food spoilage and even bosses dying of old age. He then delved into some unrealized ideas, including a beard growth system once planned for "Death Stranding 2: On the Beach."
Kojima revealed, "Originally, Sam's beard would grow longer over time, and players would have to shave him regularly, or he'd look pretty scruffy. But considering Norman Reedus is a big star, I didn't want him looking anything less than cool."
But among all these concepts, the "forgetting game" truly stole the spotlight. Kojima explained that this game would demand constant, intensive play. If you took a long break, your protagonist would start forgetting how to even function, let alone their mission.

"If you don't play for a few days, your character might forget how to shoot, and eventually won't even be able to move," he chuckled, suggesting players might actually need to take time off work just to keep up!
Kojima also tossed out other time-related game ideas, like characters aging from birth to old age, with physical abilities fluctuating but wisdom and experience growing. Or an idle game focused on brewing sake or making cheese, highlighting the beauty of long maturation and the art of waiting.
