Most of today's crop is either hashtag-spam shorts, AI-narrated filler, or vague personal vlogs. The TableCroissants mini-documentary on Team Fortress 2 sniper duels stands out as the one entry that actually promises to teach something specific: the mechanics, psychology, and unwritten etiquette of one of the most iconic 1v1 subgames in multiplayer FPS history.

TF2's Sniper class has been the subject of nearly two decades of community study — headshot hitboxes, scope-in timing, quickscope versus fully-charged shots, sightline theory, and the strange mutual-respect rituals that develop when two snipers repeatedly duel across a map. A good mini-doc on the topic can pull from a genuinely deep well: pro Highlander play, community jump maps, and the way Valve's netcode quirks shape which duels are winnable.

The channel is small (2.6k subs) but the tongue-in-cheek framing ("the subspecies of Snipers is a fascinating study") suggests a nature-documentary parody style — a format that, when done well, teaches real game mechanics under the guise of comedy. If you've ever played TF2, or you're curious how competitive communities develop informal codes of conduct around specific mechanics, this is the pick of the batch.

Caveat: the rest of the list is notably weak today, so this wins partly by default — but it's a legitimately interesting niche topic.
