Fill - Games

In game design, 'Fill' refers to the core mechanics that occupy player engagement between major objectives. It encompasses resource gathering, crafting systems, side quests, and environmental exploration that provide substance to the game world. Well-implemented Fill creates satisfying gameplay loops and rewards incremental progress, while poor Fill feels like repetitive padding. The concept also extends to narrative, where background lore and character interactions fill out the story's emotional depth. Ultimately, Fill determines whether a game feels richly immersive or hollow between its key moments.
