Just trying to gross you out here
But I always knew games were good for us in that way. Of course books shouldn't be "replaced" or anything, nothing's going to get replaced. But if you look at the sheer control you are required to have over your game if you're expected to finish/beat it, it's pretty obvious you're learning quite some skills in controlling your body and mind.
Of course, some games will be better at this than others...
