A game creation system (GCS) is a consumer-targeted game engine and a set of specialized design tools (and sometimes a light scripting language), engineered for the rapid iteration of user-derived video games. Examples include Novashell and Pie in the Sky.
Unlike more developer-oriented game engines, game creation systems promise an easy entry point for novice or hobbyist game designers, with often little to no coding required for simple behaviors. Although initially stigmatized, all-in-one game creation systems have gained some legitimacy with the central role of Unity, Construct, and GameMaker: Studio in the growth of the indie game development community. Currently the Independent Games Festival recognizes games produced with similar platforms.
Early game creation systems such as Broderbund's The Arcade Machine (1982), Pinball Construction Set (1983), ASCII's War Game Construction Kit (1983),Thunder Force Construction (1984),Adventure Construction Set (1984), Garry Kitchen's GameMaker (1985), Wargame Construction Set (1986), Shoot'Em-Up Construction Kit (1987), Mamirin / Dungeon Manjirou (1988), and Arcade Game Construction Kit (1988) appeared in the 1980s on home computers. 3D Construction Kit was released on the ZX Spectrum in 1991, and contained a full polygon-based world creation tool. Most of these early design frameworks are specific to one or another genre.
