We need less realistic and more realism.

That is things in a game world, however fantastical should behave the way your mind expects. I should slip on a banana in Mario Kart because it happens in real life.

This is taken to the nth degree by titles like Breath of the Wild where interactions, in-game physics and even the weather all behave as you would expect and yet the game is about an elf with a magic sword fighting to destroy a demonic pig.
