When my dad brought home a Commodore Pet 2001 in 1977, I was six years old. I figured out pretty quickly how to load and play some of the games from cassette. One game in particular, called "Dungeon" which was a pretty simple roguelike (although it actually pre-dates Rogue), I liked a lot. But the instant I figured out I could change the game by simply deleting lines of code, I was completely fascinated. Only deleting certain lines of code would work, others would make it not run. Why? How does all this work? Suddenly the game itself wasn't particularly interesting. I was hooked on figuring out the game behind the game. It didn't take long for me to start digging deeper and deeper into Computer Science.
