Those are some impressive specials. I tried doing a Rock, Paper, Scissors game. I found it disappointing that I couldn't implement what I envisioned in the 20 command special. I knew it would be done with multiple scripts but I wanted to save the others for other specials.
There is a thread in this forum about btbuilder. You can find it at http://www.identicalsoftware.com/btbuilder/. It is an open source implementation of the Bard's Tale Construction Set with the aim to eventually recreate all the original games.
