It is interesting to see no games were developed using C, C++ or Java and outside of JS for web games it is all C# and Unity.

I don't really follow game dev, is C# popular in the industry then? I know a couple of popular indie games were developed using C# and Unity but has it made its way into the bigger studios?

As I understand it, Unity is crazy gargantuan huge, and C# basically came along for the ride. Many extremely popular recent games were made in Unity, including Cuphead, Kerbal Space Program, Cities Skylines, Firewatch, Monument Valley, Ori and the Blind Forest, Superhot, and more.

Yeah, I remember playing around with Unity when their main selling point was being a game engine for the Mac. It’s insane how they went from niche novelty to utterly dominating an industry.

Super Mario Run, Pokemon GO, and Hearthstone are also made with Unity.

On top of this, Unity is fantastic for prototyping, making it much better suited for game jams than most other engines.

Both "Overall Winner" and "Best innovation" were written in Godot with GDScript

Major "AAA" games are C++, C# is used because of Unity but behind the scene it's C++. Also Unity is popular in mobile but not that much in console games.

Yup, pretty much any modern game is going to have a scripting/rapid prototype layer at the top. Unity's just happens to be C#.

I'm guessing that the time-crunch of being a "game jam" drove most of the participant's decisions to use Unity and C#.
