10 Free and Open Source Game Engines – Part 2

Game engines offer huge benefits to game developers. The main functionality they provide is the library of core functions used in a computer game. This often includes a realtime rendering engine for 2D or 3D graphics, physics engine with collision detection, a character animation system, scene graph, sound, artificial intelligence, threading, networking, input, streaming localization support, debugging tools, integration with languages, and the provision of performance monitoring and optimization tools.

Game engines play a crucial role in the fast creation and development of computer games. As they offer a collection of visual development tools, and are often presented in an integrated development environment, they vastly accelerate the development of games. Game engines are referred to as “game middleware” because they provide a flexible and reusable software platform.

We covered game engines in this article. This article recommends more great game engines.

Let’s explore these additional 10 game engines. For each engine we have compiled its own portal page, a full description with an in-depth analysis of its features, a screen shot of the program in action, together with links to relevant resources.
