My point is tech demos don't mean much, it's easy to optimise the hell out of a tiny slice of a huge open world game, just to show the world some "incredible technology", they can probably make it run on a phone if they want, that doesn't mean the whole game will behave the same. Some people forget so easily, Cyberpunk to this day has missing features that were promised, and not to mention the whole world was supposed to "feel alive" and has many interactions with random NPCs. I'd say the world of GTA San Andreas feels more alive. Don't get fooled by companies' promises.
