I'm still waiting for anyone to give me a compelling reason they should acquire Kojima Productions beyond "It's Kojima" or "MGS". Cuz Death Stranding was absolutely NOT it.
Maybe if you saw it through an objective lens rather than your narrow subjective opinion you'd might have a different stance. It's about his longstanding working relationship with Sony and his franchises being tied to Playstation. That's where the majority of his audience lies and that's why him and his studio is a great fit for SIE. What you think about Death Stranding means absolutely nothing in the grander scheme of things.
