I was thinking of making opening doors a bit more eventful, and then remembered an old game I have in the back of my games cabinet, Dungeon Quest. I won't go into the whole game here, but one of the mechanics was that whenever a hero wanted to open a door, he would draw a cards from the Doors deck to see what happens. Results if I recall correctly were "Door opens", "Door jammed", "Door Trapped" and "Shuffle the deck and draw another card" (so cards put at the bottom of the pile never resulted in the same sequence).
For HQ, I would consider the cards above as well as "Door locked" and "Wandering monster" results. A locked door could be opened with a key, broken down or its lock picked (and suddenly a thief hero makes a lot more sense!); a jammed door would have to be broken down.
Would this mechanic play well in HQ? Or do you think this would bog down the game too much? For one, I guess it depends on the ratio of "door opens" to other cards of course. But if a door could possibly have an explosive or poison cloud trap on it (or some other area effect), it might help against the "all heroes at the door" syndrome
