Critically Acclaimed PlayStation Exclusive Struggling on PC

Sony's big action games have done great on PC. It's the lower profile games that have launched with little to modest success. Also the lack of marketing didn't hurt the first few games as the novelty of a port at all basically created publicity. It's becoming more and more expected now though, so they'll need to do some marketing if they want big numbers at launch. Doesn't need to be a big campaign but just find an excuse to generate extra discussion online.

Spider-man, God of War, Horizon Zero Dawn all did amazingly. Even Days Gone did great. Uncharted and The Last of Us both had port issues at launch; Uncharted is in good shape now but TLoU still needs some work (and likely a bit of marketing to let people know that). Returnal is niche and I expect it will do well in the long run, but was never going to do gangbusters at launch. Sackboy and Ratchet & Clank aren't generally the types of games I'd expect to do particularly well on PC.
