Sony is piloting a new review system on the PS Store, allowing players to write detailed reviews similar to Steam’s format. Currently, only those who purchased digital copies of select games like Helldivers 2, Final Fantasy VII: Rebirth, and Resident Evil 4 can leave reviews. Sony is considering including gameplay hours with reviews to combat review bombing, though this may be challenging due to issues with the PS5’s playtime counter.

When did PlayStation start allowing written reviews? Seems to only be allowed for few games on their store pages for now.
