Godot
Godot is a 2D and 3D, cross-platform, free and open-source game engine released under the MIT license. Godot's development was started by Juan 'reduz' Linietsky and Ariel 'punto' Manzur in 2007, with the source code being initially released in 2014, under the MIT license.
The name "Godot" was chosen due to its relation to Samuel Beckett's play Waiting for Godot, as it represents the never-ending wish of adding new features in the engine, that would get it closer to an exhaustive product, but never will.
