COMPLETION PERCENTAGE
A visible tally of how much of the game's content — collectibles, map areas, quests, achievements — the player has finished, usually shown per-region or as a single global number.

Grand Theft Auto popularized the global 100% stat, Metroid ties its percentage to item pickups and uses it to gate alternate endings, and modern open-world games like Assassin's Creed show per-district completion. Designers use the number to make invisible content visible: a district at 93% tells the player something is still hidden there, converting aimless wandering into directed search. It also serves completionists as a long-tail goal after the credits. Key decisions: what counts toward the percentage (padding it with filler collectibles cheapens it), whether to show it before or only after the main story, and whether 100% earns a tangible reward or just the number itself. Pitfall: a completion stat that tracks tedious content becomes an obligation generator — players grind joyless checklists because the number demands it, then resent the game for it.
