@Mordecai: The flip side to that is coming upon a truly excellent dungeon for which you are completely overpowered, ruining the experience. I recall a fantastic Morrowind dungeon with an amazing vertical design and a green sword at the end. By the time I discovered it, I blew through without a scratch and the sword was useless to me. The disappointment stays with me to this day as an experience that I missed out on.
The flip side is Oblivion, where I took my time getting to the city with the first Oblivion gate that gets overrun by daemon. I was probably 10 levels higher than the devs expected, so all the daemon were jacked up too.
The NPCs are supposed to assist you, but all the daemon slaughtered them instantly, leaving me to spend hours isolating each daemon individually so I could kill it and proceed with the quest. This should have been a 20 minute battle, but was ruined due to scaling.
I don't know what the solution is, but it needs to be done with much thought and testing.
'I am' is reportedly the shortest sentence in the English language. Could it be that 'I do' is the longest sentence? - GC
