ADAPTIVE DIFFICULTY
The game silently adjusts challenge — enemy counts, damage, item drops, AI aggression — based on how the player is performing, keeping them inside a target tension band without a visible difficulty setting.

Resident Evil 4 famously scales enemy aggression and ammo drops with a hidden rank that rises when the player dominates and falls after deaths, and Left 4 Dead's AI Director paces zombie hordes, item spawns, and quiet moments from a model of team stress. Designers use adaptive difficulty to keep a wide skill range of players in flow, smooth over difficulty spikes that playtesting missed, and manufacture dramatic pacing (calms before storms) that fixed spawn tables can't. Key decisions: which knobs the system may touch (resource drops feel fairer to adjust than enemy health mid-fight), how fast it reacts, and above all whether to disclose it — hidden systems preserve immersion but can feel unfair or patronizing when discovered. Pitfall: punishing skilled play — if playing well visibly makes the game harder and hoarding resources makes it stingier, players learn to sandbag, which is the opposite of engagement.
