Tenuous relevance, but a different stock market game written in BASIC on the Apple II (well, I only had access to the Franklin Ace clone) was my initial motivation at age 10 or so to try programming. It was a pretty thrilling amount of power to a 10-year-old to be able to rename all the companies after my friends or whatever jokes I wanted, and next to alter the rules to get more money. It’s a good thing BASIC was everywhere in the 80s — so many books and computer manuals had enough information that it was easy to find a source to learn the (no pun intended) basics.
