Agreed. Immersion in a game world, at least for me, is less about how accurately it visually reflects reality and more about how detailed the overall world feels -- whether the designers have crafted worlds that feel like they live and breathe without you, that you could imagine inhabiting as someone other than the protagonist. For instance, I can imagine what it would be like to live in Cyberpunk 2077's Night City, whether I was a merc like V or just one of the nobodies trying to get by that you pass on the street; I can imagine living in Dishonored's Dunwall (or the sequel's Karnaca) in the chaos and uncertainty of their plagues; I can put myself in the shoes of one of the faceless, downtrodden members of the proletariat of Coalition-occupied Revachol in Disco Elysium; a lot of AAA games, on the other hand, feel like theme park rides--well-crafted experiences that are enjoyable but don't stick with you and discourage you from thinking too deeply about them because they don't withstand much scrutiny. But Cyberpunk 2077 is evidence that they don't have to be that way, and Dishonored and Disco Elysium are equally evidence that you don't need a half-billion-dollar budget and photorealistic graphics to create immersive worlds.

(edited to clarify that I'm not laboring under the misapprehension that Cyberpunk 2077 isn't a AAA game)
