ZGameEditor lets you create 3D games with procedural content that have a redistributable size of 64 KiB or less. It consists of a lightweight OpenGL-powered engine that runs on Windows, Mac, Linux & Android, and a portable Windows IDE featuring real-time editing. ZGameEditor's design philosophy is that users should be able to create applications without requiring lots of programming-knowledge. Besides games, ZGE lets you create screensavers and animations to use in other software. ZGE is Free and Open Source Software.
