ezEngine -- The Easiest C++ Game Engine?

ezEngine is an open-source and free 3D game engine primarily designed for ease of use in C++. It supports scripting languages like C++ and Angel Script, and includes a modular, plugin-based architecture that facilitates custom extensions. Key features include component-driven development, prefabs, visual state machines for game logic, and a variety of built-in tools and templates. As of the latest release, the engine is focused on Windows, but a Linux port is in process.
