One of the reasons that died is that last gen went from the tech designed to be the most powerful thing available (on PS360) to CPUs that were bad even for 2013 mid-range laptops. Current gen is better but not that much better. Even on high end PCs GPU advancements are quickly outpacing CPUs.
Another reason is that open world has replaced linear as the norm, it's hard to do this shit when it has to be completely dynamic.
