Trying to. You will not find many game frameworks for Lisp, but all of the pieces are there. I mainly use Lisps for livecoding. I am currently trying to learn Extempore for livecoding. It has two languages: xtlang, a Lisp language that is strongly typed and compiled for close to C speed via LLVM, and a scheme for doing more high-level scripting stuff in the Extempore environment [1]. There are binaries available for all platforms. I run it in Spacemacs on Windows 8.1. It's very snappy, and powerful, for coding music/sound at the signal or note level, and it has OpenGL and Nanovg for graphics. Watch Andrew Sorensen rock it on YouTube or Vimeo - just search for Extempore and/or Andrew Sorensen. I hope there will be a way to distribute things created with it someday. Then it would be a kick ass game dev platform. I tried Racket and SBCL brie

fly specifically for games. Both are very capable. I will probably go back to SBCL, since it worked well with SDL2, OpenGL and was fast on both my Windows and Linux boxes. CEPL is great for working with OpenGL in Lisp [2]. I would love to use PicoLisp. I almost did use it for a game jam, but you would need to create the game framework from the pieces it has, and again, the Posix / Windows issue. I'm really hoping for the Midipix solution. You can learn PicoLisp fast in a week or so by following along with the two great books - PicoLisp Examples, and PicoLisp Works. The PDFs are freely available on Scribd and the source code is available online [3][4]. Even Erlang is available as a Lisp - LFE, or Lisp Flavored Erlang, created by one of the original designers of Erlang, Robert Virding. Would be great for a game server with many connections. Elixir is becoming very popular but LFE has true macros, and why not, it's a Lisp!
