Australian developer House House's cooperative title Big Walk has sold one million copies within a week of launch, significantly outpacing their previous breakthrough success Untitled Goose Game, which took three months to reach the same sales milestone. The rapid adoption is bolstered by the game's availability as a free PlayStation Plus offering alongside Nintendo Switch 2, which provides broad platform access and eliminates purchase barriers for a substantial portion of the player base.

Big Walk ranks among 2026's successful indie releases, though it trails PC exclusives like Meccha Chameleon (1M in four days). Critics attribute its appeal to its design philosophy—a peaceful, cooperative-only experience without fail states, matchmaking complications, or competitive elements. This positioning aligns with a demonstrable trend toward relaxation-focused multiplayer games that prioritise accessibility and social play over challenge-based progression.
