Hideo Kojima reveals why his partnership with Sony soured after PlayStation dropped the Physint engine, detailing the impact on development and future collaborations.

Renowned game creator Hideo Kojima sat down for an exclusive interview this week, shedding light on the strained relationship with Sony Interactive Entertainment that has simmered since the PlayStation platform discontinued support for the Physint physics engine.
Background to the rift
Kojima, whose partnership with Sony produced landmark titles such as the Metal Gear Solid series and the early Death Stranding entries, has long been a vocal advocate of cutting‑edge technology in interactive entertainment. When Sony announced it would phase out Physint—a middleware solution that powered realistic environmental effects in several of his games—Kojima said the decision caught his studio off guard.
What Kojima revealed
During the conversation, Kojima described a series of internal meetings where Sony’s hardware team presented a roadmap that no longer included Physint. He explained that the move forced his development team to re‑engineer core gameplay systems, stretching timelines and budgets.
“We were built around that technology,” Kojima told the interviewer. “When the platform removed it, we had to scramble to find an alternative that could deliver the same level of fidelity.” He added that the shift strained the collaborative spirit that had defined the partnership for decades.
Impact on future projects
Kojima confirmed that the fallout has led his studio to explore multi‑platform releases more aggressively, seeking engines that are not tied to a single console’s ecosystem. While he remains optimistic about the possibility of working with Sony again, he emphasized that any future collaboration would require clear technical alignment from the outset.
He also hinted that his next project will leverage a proprietary physics solution, allowing greater flexibility across PlayStation, Xbox, and PC.
Industry reaction
The interview has sparked discussion among developers about the risks of relying heavily on console‑specific middleware. Analysts note that Sony’s decision reflects a broader industry trend toward platform‑agnostic tools, which could reshape how major franchises are built.
For fans, Kojima’s candidness offers a rare glimpse into the behind‑the‑scenes negotiations that shape the games they love.
