I mean, they are dong cross release for stuff but there was new stuff. PS5 also had Sackboy and Spider-Man:Miles Morales and yes there are PS4 versions but they do look and run much improved on PS5 beyond simple resolution. Miles particularly looks very good with the raytracing modes. MS is the one that really stumbled there though as they had no first party games at all this fall, not even new crossgen ones, though I guess you could maybe count Gears Tactics which came out on PC in the spring and consoles in the fall.
Microsoft’s biggest game release of the year was in the summer and was PC only, oddly enough. Flight Simulator if you couldn’t figure that out.
