Sacred Haven of Debauchery

Wolf, at least remember Gothic. There was some kind of fighting there, and you can't just rush an Orc with a dagger.

I don't know why you quoted that specific phrase of mine, as it's about something completely different.
But yes, I didn't particularly like Oblivion for that reason either - you can always kill everyone. As soon as you level up, a weak creature disappears and a stronger one appears in its place, and there aren't places you can only access after reaching a certain level, for example.
