"A cross-platform (desktop, mobile, console) 3D and 2D game engine. Powerful visual editor. Support for glTF, X3D, Spine and more. Fast clean code using modern Pascal. Free and open-source." — official site.
Fun fact: not only is the game engine and exports supported natively on Linux, it's mostly developed on Linux too.
Some of what's new coming to the 7.0 release which is now on it's second Alpha build includes:
- Integrated Sprite Sheet Editor.

Great to see more and more free and open source tools available and improving for game development. Even better when they work nicely cross-platform for both developing and testing games. CGE might not be the most well-known game engine, but it deserves a bit of a spotlight to show there's more than one way to build a game with FOSS.
