How recent are we talking about? Did you miss Breath of the Wild? Super Mario Odyssey? The Last of Us 2? Red Dead Redemption 2? Hollow Knight? Elden Ring? Half Life Alyx? Hell, Pokemon Go qualifies for cultural recognition.
I think Pokémon Go was a much more visible and impactful phenomenon (in certain places) than anything else on your list. This might be different to "cultural importance" depending on your definition.
I mean did random churches and libraries have "Playing Red Dead Redemption 2 is not allowed here" signs up?
Were there flash mobs in NYC playing Half Life Alyx?
