Godot is one of the most awe inspiring open source projects out there. It's vast, but yet so well documented, user friendly, and incredibly well maintained. If you're thinking about using Unity for something, but was weary of the business model, Godot will surprise you.
I've been messing around with Godot for a hobby project over the past week, and I've been pretty impressed with it so far. After using it for a bit, I think it'd be interesting to see more non-game applications written in the Godot engine. It's simple to export your project to other platforms, and being a game engine, it has all the graphical customization the web devs say they use electron for. The built-in Godot IDE is actually built with Godot. Another benefit is that it has a C compatible API, so it's fairly simple to write CPU intensive tasks in a more performant language and call them from the included scripting language.
This is looking really nice. I'm a bit sad that Godot crashes on my kids' MacBook Air (apparently there's a bug in the URL filtering subsystem that takes down the entire OS when Godot tries to reach its library - see <a href="https://github.com/godotengine/godot/issues/24890" rel="nofollow">https://github.com/godotengine/godot/issues/24890</a> for details)
One of the hopes of Vulkan on Godot is a higher performance API on mobile. Apple is a sticky company to develop for and it isn't practical to have direct support for metal, but moltenVK might allow for vulkan based games to run on it. If this abstraction really is possible then vulkan seems to be an excellent choice for supporting multiple platforms. I'm nervous about it happening until I actually see it happen. There is also not very much discussion on this front, even though it must affect many people trying to make games for mobile.
I gave up on godot (for now) because it lacks basic math functions like mat4/vec4 operations and access to the projection matrix in the camera.<p>Switched to unreal, but it's taking way me way longer to figure out.
