Godot

Now with version 4, it is the most complete and universal engine in the world of FOSS.

It is small, efficient, and has a helpful community.

There are two versions of the engine which are currently supported.

Now there is the 4th generation, which has been redesigned in many ways, with Vulkan as the main graphics backend, and the gdScript which was redesigned, faster and more reliable than before.

The 3rd series, which is the old version, is now mainly in maintenance mode. God for older computers with integrated graphics but it will get too many new features like the 4.x.

Some people say that there is a lack of documentation, but it was true at the beginning of the project. Now the problem does not exist.

The cons, sometimes due to new features there is the possibility, that the project will break with the new version of the engine and there will be no possibility of reversing. But in the end, it is possible to stick with one version for longer.
