Not to imply playing video games is as intellectually stimulating as reading, but I feel like some games really challenge you in a positive manner. The ability to manage your inventory, interact with characters, make choices and deal with the consequences are all great for expanding your mind. Essentially, playing some RPGs (I feel) can make you a slightly better person whereas I have a hard time seeing the intellectual value in something like Fortnite.
That's absolutely true. The game matters. Games with a strong story can put you in the role of someone with unfamiliar backgrounds and challenges where other games are more about reflexes. I think they likely all have some sort of value. Fine motor skills, teamwork, dealing with success/failure, spatial reasoning, etc. but a good story is great for lessons you can't get with space invaders or bejeweled.

Have you tried playing Minecraft with mods? You know, something like GT New Horizons or Omnifactory. Those will melt your brain. They are the equivalent of climbing a mountain vs taking a leisurely stroll (reading). The idea that reading would be as mentally stimulating as that sounds ridiculous to me.
"Some RPGs". You have seen nothing. Nothing at all.
