What other game could I actually go into anyone’s home and see exactly how they live? What other game could I play that lets me pick up and look at, in detail, anything that isn’t nailed down (forks, pieces of paper, charcoal, etc)? What other games create a living breathing world where characters have full schedules and lives programmed into them (more games are coming out with these types of features though)?

People just like being able to exist in a detailed world like that, and almost no other game comes close to that level of immersion imo.
