Adventureland and Pirate Adventure were both originally done in BASIC and the interpreter with the compiled language (it reduced it to numbers) was on the tape. I did have some extremely clever folks reverse engineer my language and then write games in it! Hat tip to Alvin Files and William Demas amongst others!
Pirate Adventure was the first game I had on my Atari 800. I really loved it. I still remember coming across the terms "pieces of eight" and "flotsam and jetsam" and having to ask my mom what they meant. I seem to recall it was my first encounter with the the word "flat" meaning apartment. My vocabulary was thus improved by your work. Thanks!
