FLOSS game engines, like the Godot game engine, as well as libraries, like SDL, are increasingly common in game development, even proprietary ones.

In recent years, this changed and availability of open source tools like Blender, game engines and libraries drove open source and independent video gaming. In the past (before the 2000s) a challenge to build high-quality content for games was the missing availability or the excessive price for tools like 3D modeller or toolsets for level design. The consequence of this is that open-source games often take longer to mature, are less common and often lack the production value of commercial titles. Many open-source games are volunteer-run projects, and as such, developers of free games are often hobbyists and enthusiasts.

In general, open-source games are developed by relatively small groups of people in their free time, with profit not being the main focus. See also: List of commercial video games with available source code
