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.

Gamedev in Lisp. Part 1: ECS and Metalinguistic Abstraction
A recent, notable game made in Lisp is Kandria: https://store.steampowered.com/app/1261430/Kandria/ / https://github.com/Shirakumo/kandria

We need to talk about parentheses
Examples (for Common Lisp, so not citing Emacs): reddit v1, Google's ITA Software that powers airfare search engines (Kayak, Orbitz…), Postgres' pgloader (http://pgloader.io/), which was re-written from Python to Common Lisp, Opus Modus for music composition, the Maxima CAS, PTC 3D designer CAD software (used by big brands worldwide), Grammarly, Mirai, the 3D editor that designed Gollum's face, the ScoreCloud app that lets you whistle or play an instrument and get the music score,
but also the ACL2 theorem prover, used in the industry since the 90s, NASA's PVS provers and SPIKE scheduler used for Hubble and JWT, many companies in Quantum Computing, companies like SISCOG, who plans the transportation systems of european metropolis' underground since the 80s, Ravenpack who's into big-data analysis for financial services (they might be hiring), Keepit (https://www.keepit.com/), Pocket Change (Japan, https://www.pocket-change.jp/en/), the new Feetr in trading (https://feetr.io/, you can search HN), Airbus, Alstom, Planisware (https://planisware.com),
or also the open-source screenshotbot (https://screenshotbot.io), the Kandria game (https://kandria.com/),
and the companies in https://github.com/azzamsa/awesome-lisp-companies and on LispWorks and Allegro's Success Stories.

Factorio: Space Age
> The source is not publicly available, no. It‘s still being actively developed and sold after all.
Those two are definitely not incompatible. Take Karia[0] for example, which is fully Free Software[1].

The battlebit discord anticheat “helpers” everybody.
I’ve seen a 1 person team support steam deck controls with a game written in lisp kandria. The battlebit devs have much better tools supporting steam deck using the unity engine. The controls for the steam deck is definitely not the main reason to abandon Linux, the anti cheat stuff seams to be the only thing in the way.

best lisp or scheme for web game dev?
I don't know about "best", but the work that the Kandria dev has put into CL libraries to create his game has been impressive to see.

Looking for multi-paradigm languages that have reliable tail-call optimization
For what it's worth, I'd take a look at Common Lisp. It's perhaps less functionally-minded than OCaml, but I don't think it's fair to call it imperative. You'll encounter similar-looking patterns. There aren't loads of games for CL, but I've heard Kandria is super (https://github.com/Shirakumo/kandria), as well as being a great example project.
- Kandria, an action RPG made with Common Lisp is now available!

The thing is, if you start with Common Lisp, it's pretty easy to write a DSL that adds the constraints and provides the guarantees that you need. [..] Maybe all I had to do to turn CL into Haskell is implement the Hindley-Milner algorithm.

Hell Is Other REPLs
I used to use CL quite a bit, but have since abandoned it for Haskell, so I'm a bit biased.
There's a number of issues with that:
- I'd be missing all the optimizations that can be performed due to purity.
- There's more to Haskell's type system than just vanilla Hindley-Milner, and the implementation of it isn't particularly trivial. https://github.com/stylewarning/coalton is the closest thing and it's still missing a large amount of the type system.
- Doing the implementation would be a significant amount of work to get it to integrate well with the language, and it would be a layer tightly glued on top instead of integrated with the language.
- A major part of Haskell is the standard library, a good chunk of the semantics of Haskell people use on a day to day basis, like monads and etc, are a part of the standard library.

Six years of professional Clojure development
This looks like something Common Lisp does better, however I have too little Clojure experience to compare. CL (and SBCL in particular) does "good enough" static type checks, it throws warning at compile time (when we compile one function with a keystroke). We can also precise our function types gradually. It isn't a HM type system (Coalton[1] could be it) but it's already great (compared to no compile-time types at all).
Oh, about interactive development: that's sure, CL shines here. Objects get updated (lazily) after a class change, we can install Quicklisp libraries without restarting the image, etc. It's very smooth.
