An example of a game I think should have been a success but wasn't is
Counter Spy released for the PS4. It's a really fun game and just stumbled on it in the PS Now catalog.
This is a great example! I took a look at the trailer and I think the artstyle and gameplay looks really interesting. I took a closer look at it looks like reviewers at the time had a lot of technical issues. I wonder if those issues are now fixed. Did you play it on the PS5?
I played it on a regular ps4 and there were no bugs.
