Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Do you use MonoBehaviours to implement behavior?
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!

interested in learning lisp, (specifically for games, but also for everything else including tui and gui applications for linux. currently have next to no programming knowledge, can i get forwarded some resources and some tips on what exactly i should do? any videos i should watch?
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.

Where Lisp Fails: at Turning People into Fungible Cogs.
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.

Godot appreciation post
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.

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

Compiling a Lisp to x86_64 (2020)
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

A few newbie questions about lisp
When you want to do anything that breaks the nice bubble of your Lisp image, you might want to know a bit about your operating system's programming interface. This will come in handy if you ever need to wrap a library with CFFI. There are some things that are pretty inconvenient as a rule (like dealing with any protocol that uses network byte order), but if you stay within the bubble of your Lisp image, you won't really notice them.

*UPDATE* - CL-OBJC
I'm just posting the work that I have done over the last year or so on CL-Objc. I'm still blocked from better support (e.g., passing structs by value for frameworks like UIKit). I just wanted to post what I have done online for others interested in the work or motivated to collaborate on this.

Waiting on feedback - CFFI PR
Good morning ladies and gentlemen, I have been waiting on some feedback for PR in CFFI. This feature is blocking me from reviving CL-OBJC. Any help will be appreciated. Thank you in advance.

Anyone else able to kill threads in SBCL on M1 mac?
Is that actually https://github.com/cffi/cffi/commit/33970351e71bb5f12ba56fc40270089e948ae112 ? I.e. after loading cl+ssl. (Although Hunchentoot does not interrupt threads)

Programming the Raspberry Pi GPIO pins using Common Lisp?

Updating Quicklisp Packages
FTR, on my system QL fetches CFFI 0.23.0 and the fix/error I'm talking about is https://github.com/cffi/cffi/blob/master/src/libraries.lisp#L106 and seems to have been added iin this PR https://github.com/cffi/cffi/pull/173/commits/263b38f4f2600dbacde8f2b313620c35a563c6df so the fix should be in CFFI 0.24.0 released 24 March 2021.

C: Alternatively (more difficult) you could try to wrap the underlying C layers of either of those mentioned under Python with CFFI. The C-based game engine, Raylib, is also wrappable this way. I finished a super cool walking simulator in CL with that, but it is more tedious than the others since raylib is really barebones.

Common Lisp
I feel inspired to start Lisp after being disappointed with the "open" source scene of 2021. I'd rather pay LispWorks a yearly fee and be left alone than dealing with unbalanced people in the Python space. The free Lisp implementations also look somewhat isolated from the ideological wars.
However, a C interface is required. Is this one the recommended solution? Is it really portable?
https://common-lisp.net/project/cffi/
What is the speed compared to a Python C extension? Are implementation-specific C interfaces faster (I guess they are)?
Sorry for so many questions, but these can usually only be answered by people who have actually used the interface.
What are some alternatives?
