Your brain has a RAM limit, and bad game design fills it with UI noise instead of actual gameplay.
Cognitive load refers to the total amount of mental processing a task demands. In gaming, every system, menu, status effect, button combination, and on-screen element competes for the player's limited cognitive bandwidth. When a game's cognitive load exceeds capacity, players feel overwhelmed, confused, and frustrated -- not because the game is hard, but because it is mentally noisy. Great UI/UX design minimizes unnecessary cognitive load so players can spend their mental energy on actual gameplay decisions. Bad design dumps everything on screen at once and wonders why new players bounce in the tutorial.
Example
Destiny 2's mod system before simplification was a cognitive load nightmare -- dozens of mods across multiple slots with overlapping conditions. Nintendo games are masterclass in low cognitive load, introducing one mechanic at a time. Elden Ring minimizes HUD elements to keep cognitive focus on the environment and combat. By contrast, many mobile strategy games intentionally overload screens to confuse players into spending.
Why it matters
Cognitive load is the invisible wall that determines whether a game feels intuitive or impenetrable. It is not about making games easier -- it is about ensuring that complexity comes from meaningful decisions, not from deciphering interfaces. Accessibility and cognitive load are deeply linked, as reducing unnecessary mental overhead helps all players, not just those with cognitive differences.
