First adventures I played were Leisure Suit Larry I and Space Quest II. My dad had just bought an IBM PS2 Model 30 computer with some games. The sales clerk recommended some Sierra games. Unfortunately my dad wouldn't let me play Larry. After my dad had gone to work I booted up the game and I wrote down all questions and tried every possible answer
After a while I got in and finally understood why my dad wouldn't let me play! I learned some very naughty words that week...
After that I got hooked on Sierra adventures.
