Design by subtraction is a principle where everything but the core of an experience is removed. Features aren’t added for wider appeal, but are instead cut so the strengths shine without distractions. Another World is the quintessential example, with the platforming, combat, and interface kept simple, so players can become immersed in its alien world without abstract barriers. Its world is mysterious, but simple interactivity affords clarity, so the mood is of discovery rather than confusion. When highly contextual actions are required, the spell breaks, but Another World’s atmospheric core is still constructed so efficiently that nothing bears removal.
