Live service & the long tail

Fourteen mechanics originate in this window, and the newest entry in the entire dataset is from 2020, which is a claim about evidence rather than about the industry. Recent origins are synthetic in the precise sense: Breath of the Wild fuses Systemic Climbable Surfaces with Stamina Action Economy to produce Climb-Anything Stamina Traversal, and fuses Far Cry 2's propagating fire with Half-Life 2's rigid bodies to produce Systemic Elemental Chemistry. PUBG combines matchmaking with Rogue's food clock and gets the Shrinking-Circle Battle Royale; Escape from Tarkov adds permadeath to that and gets extraction. Slay the Spire merges a card game with a roguelike run. Sekiro resolves a twenty-year argument between parrying and stamina. Elsewhere, Apex Legends' Non-Verbal Ping Communication and The Last of Us Part II's Comprehensive Accessibility Suite treat access as a design surface, Fortnite drops platform walls, and Half-Life: Alyx restates the camera problem by making it the player's neck.
