What's some cool videogame features or concepts or subject matter that pushed boundaries either for the whole industry or for you personally?
I liked the "Trust/Fear" system of the 2002 John Carpenter's "The Thing" game for PC, you had to prove you weren't infected to NPCs and shit or they wouldn't trust you, or they would get so stressed by the current situation that they run away or kill themselves.
