Abstract

Contemporary game engines simulate physics exclusively within the material domain. This paper proposes a complete game mechanics framework derived from the Ki network hypothesis, in which the universe contains a pre-embedded design structure that divides reality into two co-existing domains: the material world and the Ki world (the invisible world). Applied to game design, this yields four revolutionary mechanics: (1) a dual-layer world structure where material and spirit maps co-exist in the same coordinates; (2) a magic system defined as intentional manipulation of boundary surfaces (Ma); (3) a soul system in which character Ki patterns persist after death; and (4) an ethical economy in which depth of action generates value. Commercial applications include engine plugins, IP development, and white-label licensing. Related: DOI 10.5281/zenodo.19691010, DOI 10.5281/zenodo.19691078.
