It seems Sony Interactive Entertainment is learning that the PC can be a useful platform. The platform holder tends to focus heavily on console exclusives, unlike its rival Microsoft, who is more than happy to bring games to Xbox and PC. That may change following the release of Horizon Zero Dawn on PC.
In its 2020 Corporate Report, Sony talks about a strategic direction for the company. Buried at the end of the mission statement is this interesting tidbit: "We will explore expanding our 1st party titles to the PC platform, in order to promote further growth in our profitability."
There's no details on which games will be making the transition, but it's likely that Sony will stick to only bringing over games that are rather old. I could see Days Gone, God of War, or Marvel's Spider-Man moving over to PC now that Sony is moving toward the PlayStation 5. The document hammers heavily that Sony still wants players to "select PlayStation as their platform of choice".
The PC port of Horizon Zero Dawn was successful, still sitting in the upper echelons of Steam's Top Sellers list in the 20th spot. That title seemingly made the transition because of the prior port of Death Stranding, which was also built in Guerrilla Games' Decima Engine. Horizon Zero Dawn's port wasn't as impressive as Death Stranding, but it was enough to open the series to a whole new audience, just in time for the sequel to come out on PlayStation 5.
Sony isn't the only company realizing that the PC is where it's at. Following the release of Persona 4 Golden on PC, Sega said it will be focusing more on porting old games over to the platform. "Going forward, we intend to aggressively promote the porting of previously launched titles to Steam and other new platforms. Under such direction, we would like to take multi-platform rollout in account and prepare the PC version and others from the start," said the company during an investor call.
