They've released MLB The Show 21; Returnal and Ratchet and Clank but with Horizon being delayed to 2022 I feel like this year may be one of their worst in over a decade. At least quantity wise.
There is Ghost of Tsushima as well but that is originally a 2020 game.
I feel like if Sony was able to supply enough PS5's then we wouldn't be having this conversation as I doubt they would have delayed Horizon.
With that being said, 2022 is shaping up nicely.
