Exactly,
If you have a particular style to setting up traps, doors, objects - this would guarantee that this style would be applied to all your objects in the map or game. Suppose you really like it when an object rotates or rises when you click on it, or maybe a NPC speaks his last words to you as he dies....then with a simple script you make sure that this style was consistently obeyed throughout your game. So I have used it to add "life" to objects, and NPC's making sure there is a more polished professional look and feel to the game.
You can make clever use of counters to track time, which NPC's you have spoken with, where you have been and then reference these counters with certain NPC's so they seem to know who you have spoken with, where you have been and when.....and when you save the game the counters are saved. There is a couple great events like OPEN_MAP, CLOSE_MAP and PLAYER_DEATH which could allow you to do things on every map (keeping track of time etc..) and when a player dies you can keep track of how many times he dies, and in what period of time all in a counter. So you could tell if the player was trying to glitch or just sucked....or was so good he never died....thus you could reward him.
