Personally, I am at most interested in Troman's opinion on this, since he was the one who did most of the scripting work, did some great AIs with it, and managed to bring the language itself up to current standards while documenting it all.

I'd had to do Scheme in my 1st semester and it was not really something I would recommend to everyone. It is a nice and logical language, but lots of brackets and a seemingly lack of standard constructs like arrays (caddr ftw!) reduced the fun a bit. > It may also be worth finding a language that can be > bytecode-interpreted, possibly even loading bytecode files from disk > instead of recompiling them each time the scripts are loaded by the > game.
