honestly the only thing that comes to mind is the 404 page adventure that radical dude made for mspfa. i could have sworn that sharkalien had a bardquest riff, but that doesn't seem to be the case at all. i dont think it would be the hardest sense of humour to replicate... you'd just have to have a good understanding of text adventure game writing and fantasy stuff in the vein of conan/cerebus/groo
