We did a lot of, uh, unofficial versions of these as Dungeons and Dragons-obsessed tweens and teens, resulting in some slightly maniacal, if ultimately harmless, behavior. Our pitch dark bits involved sneaking out via a window and completing a circuit of the neighborhood, which escalated into taking and leaving items stashed in various places as proof, finally culminating in a "yeah, but can you do it completely naked without being spotted?" set of dares.

Our various forest pellet free-for-alls may have resulted in one of us entering the military in some kind of scouting capacity. My personal stratagem was camouflaging myself by remaining stock still in bizarre positions and orientations, resulting in my profile not being an immediately recognizably human outline from a distance, then getting the drop on someone. Others could cover large amounts of ground without much noise, and so forth.

In retrospect, we ended up getting quite good at that kind of thing, very quickly, and with age I realize that this is probably a large part of the evolutionary history of humanity: skulking, hunting and being hunted, deception, complex strategies for evasion and capture, tracking and being trackless, first against the other animals and then likely against each other. This was likely just built-in, waiting for the right prompts to develop.
