I don't know if I will find the time for this jam but it is very tempting. I wrote a Bard's Tale Construction Set clone called Bt Builder. It has the ability to make a Bard's Tale like game. It doesn't have a lot of the restrictions found in the original version.

Hey. I hope you'll give it a go!

Thanks for the heads up on Bt Builder. I wasn't aware that it existed. I will link to it from the website.
