The gameplay3d framework is an open-source, cross-platform, 3D framework that is aimed at supporting indie game developers who want to develop desktop and mobile games.
I've been trying to find a free, open-source cross-platform game engine for quite some time, until I finally came across GamePlay3D.
I looked for a lightweight framework with a clean design, native language support and with optional scripting. I also wanted true cross-platform capabilities.
GamePlay3D is an extremely well crafted game engine and framework that has everything I looked for and then some. It is also constantly and carefully maintained by a very talented group of people.
