Garry Kitchen still has info about it here: http://www.garrykitchen.com/product_history/garry_kitchens_gamemaker.html (and there's a link to a fan page that has more info) There was at least one other adventure writer program (I think called "Adventure Writer" actually). And stuff like Take 1, Animate, Fantavision too. Can't think of others offhand, been too many years.
