I was an Inform hacker in 1998. One thing I was proud of was having NPC's that took commands like the player. All I did was change a 'open' action so that it took an NPC argument (or whatever). The NPC really would move, and the door would really open. Also, you could 'become' an NPC and play as that character. It was a hack to the library so I never bothered submitting it to Graham Nelson. However, my friend pointed me to Inform 7 the other week, and I saw they've put player-equivalent NPCs and actions into the code base! I'm glad about that!
