I still have no idea why the "photo mode" became a thing for so many games. At least with Spider-man it makes sense though.

And this is clearly a better game than the Arkham series. Batman can't take sick selfies in Crime Alley.

All modern consoles can connect to social media and some people just like to show off cool stills from games they're playing. I remember Nintendo made somewhat of a big deal about how Mario Odyssey has a dedicated photo mode.
