Tenchu Z adds Smell-o-Meter

“Apparently, way back when real ninjas roamed around the roofs of Japan, a lack of modern technology meant they had to build up a strong sense of smell to sniff out their enemies. A doctor who didn’t smell of medicine herbs must have been dodgy, right?
Tenchu Z takes this idea and turns it into a new Ki meter that, as well as displaying sound, sight and presence warning, it will also detail your smell. As you go in disguise into missions, the smell indicator shows how detectable you are by your scent.
This makes the dog in Fable 2’s idea seem better now.
