In game design, 'Mass' refers to the physical presence and weight of objects, characters, or environments that influence gameplay mechanics and player perception. It determines collision detection, physics interactions, and the sense of scale within virtual worlds. Mass can symbolize power, stability, or resistance, often used in puzzles, combat systems, or environmental storytelling to create meaningful challenges. Designers manipulate mass through attributes like density, inertia, and momentum to enhance immersion and strategic depth, making it a fundamental element in shaping player agency and world believability across genres from platformers to simulations.
