I was super into Sierra as a publisher. They seemed to back some of the highest quality games no one knew about. Ground Control, Gunman Chronicles, Homeworld, Aliens vs Predators 2, Empire Earth, Die Hard: Nakatomi Plaza, and of course Half-Life. They published some quality games.
I loved the Quest games! They were my first real introduction to the English language. Simple phrases like Open Door and feed chickens were a great way to build my basic vocabulary. I kept pestering my dad for translations until he got fed up and taught me how to use a dictionary :)
I have so many great memories playing those games, on my own and together with my dad. It really was a bonding experience.
