looped-in VS Arcadia

You can use Clojure to make whatever you want! Right now I'm using it to build a database (https://github.com/unifydb/unifydb). Previously I've used it to build a static site generator (https://github.com/obelix-site-builder/obelix) and a browser extension to show Hacker News comments for a webpage (https://github.com/jdormit/looped-in).

If ECS gets too boiler-platey for my liking I might try some of the "don't use MonoBehaviours" approaches people have suggested, perhaps with F# bundled into a .dll. I also saw that some mad scientists had bridged the gap between Clojure and Unity via a framework called Arcadia - we'll see!

arcadia adds clojure (a lisp) to unity as a scripting language. You get to use a very good and well documented 3d game engine while still scripting stuff in your game in a lisp. there's a godot version too. The blender>unity/godot pipeline is pretty easy and documented. However, these game engines themselves are a lot to learn for your first game, especially if you're doing unorthodox stuff with them such as using lisp you won't find many tutorials.

Nowadays, Clojure can be used for this sort of stuff. Arcadia has been used to make real world games. Lead developer gave a talk about it a few years ago.

Clojure started out on the CLR before the decision was made to focus on the JVM instead, and some people still maintain an unofficial ClojureCLR port. Some people used that to make Arcadia, which builds on ClojureCLR to make it work in Unity. Here's an old video of someone Clojure's REPL-driven development to make on-the-fly scene changes, kind of cool.

Arcadia uses ClojureCLR to work with Clojure in unity. Also Godot engine version.

My understanding is that the Clojure community points everyone to Arcadia[0] since it's maintained and a bit more public about what their exact goals are. Unfortunately, neither are terribly well documented and so I've not personally used either
