Don't want to derail the topic, but I also don't feel like this is worth creating a new one: Speaking of doors, is it actually possible to steal keys from NPCs and locking them out of rooms the key is for? It'd just be realistic and what you'd expect. You got the only key, and the door is locked, so the AI without the key shouldn't get in. I know that I tried it with the priest in Tears of St. Lucia, but even though I got his key and locked the door from inside, he still got into the room no problem. Thinking about it I'd imagine there are a lot of potential problems this possibilty could create. How does the AI react? Where does it go? For some reason though I had the feeling it was this way in the original (T2 at least, haven't played much T1... those annoying zombies). Is that an oversight, a design choice, or simply something you considered and think is too difficult/impossible to implement?
