Ok I suppose you're right.
But forget about enemy level scaling, how do you guys feel about the dungeon level lock? If I just happen to enter it at a low level, get half way through, leave, then return at a higher level would the monsters inside stay at a super low level? That seems like a really bad idea ...
Actually, that sounds like the right way to do it, to me. Come back later when you're stronger - you should beat the crap out of the dudes you already knew were living there. :shrug:

Most "non-level-scaled" games are very linear - like console JRPGs. You start in Region 1, fighting monsters that are challenging for your level. Once you're strong enough, you graduate to Region 2 - stronger monsters to provide you a bigger challenge. And as you get stronger (and beat boss fights or whatever keeps you from moving on), you progress from region to region. But the monsters are locked within each area - if you go back to the beginning zone, you'll utterly curbstomp the level 1 enemies there. Nothing ever changes. That's what non-scaled games are like.
Doesn't really work well for "open world" games, where you can wander around at will. Some sort of level scaling is useful.... but, as nearly everyone is aware, Oblivion went about it in a completely hamhanded manner.
