I have no idea what that means, or in whatever context it's used for now. It's just the only good stealth game to release since Splinter Cell Double Agent V2. If you're generous Kojima made a good game with Ground Zeroes, the Styx games were an admirable enough effort with its budget. Hitman is within a specific sub genre making it hard to pin down, similarly to how Commandos has it's own niche
We haven't gotten any light/shadow intensity meter and sound based meter REAL stealth games since a long ass time ago. It's good because it's the only thing that exists currently. Maybe someone will figure out Thief one day.
