I think RPGs can be very neat at stealth.
Mouseguard treats the subtle approach as an extended conflict: the same as combat. You have a pool of 'hit points' representing how well you are hidden. The opposition rolls to remove those points, and at zero, the group has been found. During the conflict, characters can use different maneuvers to 'defend' the pool, meaning they keep out of sight, or they can make actions to 'attack', meaning they accomplish some of their goals while hidden.
Some FATE-based systems just jump to the action. This is especially handy if only some of the characters are stealth-flavored. The ninja character just decides when and where she wants to appear out of thin air. The master of disguises declares at his convenience, which minor enemy was actually him in disguise all along.
Another interesting approach is of course Blades in the Dark -- which is heavily and explicitly inspired by the Dishonored games.
When I was reading the article, my mind immediately went to Mouseguard.
