metalisp
GOAL is a good link regarding the topic for sure - one of the few times a successful game was made with involvement of lisp as far as i know. allot of it is coming from naughty dogs.
i am pretty sure there are a handful of engines and ways to make a game with lisp, i am more interested in where the potential for lisp in serious [in the sense of commercially viable / the best choice] game development lies.
for example i think the most promising way is as a scripting language, with the engine written in something closer to metal [and memory], but using lisp for the gameplay content. i also think 2) has potential but will be more niche, while 3) and 4) seem to have allot more tradeoffs.
