The Importance of Emergence in Video Games

I'm more interested in understanding the different effect they have on us than the way they work. I think there's something to the idea of how many emergent systems are in the game and then does the narrative allow for this kind of gameplay. In Divinity Original Sin 2 because it has this like deeply simulated world there's a really complex dialogue system, reputation system individual reputation for each character everyone remembers you. The father of the genre is Warren Specter but started with games like Ultima Underworld and System Shock before his Deus Ex.
