Yes, how much fun folks could have if you could connect a Repl into your game and arbitrarily change the rules on the fly!

(shameless plug alert) This is how my WIP (verrrry WIP) game engine written in Guile Scheme works. It is built explicitly to enable iterative, live development. 2 year old video of a precursor to the current project: https://dthompson.us/functional-reactive-programming-in-scheme-with-guile-2d.html https://dthompson.us/functional-reactive-programming-in-sche... Simple example program: https://git.dthompson.us/sly.git/blob/HEAD:/examples/simple.scm https://git.dthompson.us/sly.git/blob/HEAD:/examples/simple.... More complicated minesweeper example: https://git.dthompson.us/sly.git/blob/HEAD:/examples/mines/mines.scm https://git.dthompson.us/sly.git/blob/HEAD:/examples/mines/m... Home page: https://dthompson.us/pages/software/sly.html https://dthompson.us/pages/software/sly.html Hoping to get a 0.2 release out the door in time for the Lisp Game Jam coming up in April.

You can do that right now with Love2D and a stub game loop that sources the actual implementations every second or two.

  That is a far cry from a REPL.

    It's better than a REPL, that allows you to write a game completely live. I'm not sure what you think is lost since you didn't back up what you are saying with anything.

      It is strictly less powerful than a REPL. Claiming that you can't live code a game at a REPL is false, because I do it on a regular basis. When I write games in Scheme, I use a REPL to write the game live, doing all of my editing within Emacs. I do not have to save files for the code to be evaluated, I just press a keystroke to evaluate the specific form I'm interested in. I can evaluate more fine-grained sections of code, not only entire files.

        Pressing a keystroke is all it takes to save a file. Also if you are selectively executing parts of files, how is it that you are editing the live running source code?
