Microsoft has been releasing the majority of its first-party titles on both Xbox and Windows 10 for some time now, and it seems Sony has also now got eyes on the growing PC gaming market, as it states it intends to explore expanding more first-party titles onto PC going forward.
The news comes from a 2020 corporate filing that states the company intends to "explore expanding our 1st party titles to the PC platform in order to promote further growth and profitability." Indeed, recent PS exclusives such as Death Stranding and Horizon Zero Dawn have done really well on PC, so it seems like a natural area for growth.
Third-party developers such as SEGA have also started to see that PC is a growing market in recent years, releasing their back catalogue of games onto the Steam platform.
According to the report, "Competition from online PC games and players from other industries is expected to continue to intensify." Presumably, Sony is eyeing up the PC as an untapped market that it sees as unlikely to convert to its own platform.
There's still no guarantee that any first-party games are on their way to PC just yet, though, but it certainly seems Sony is giving the concept some serious thought.
