In one way, I'm glad I won't be able to exploit the way I "planned" to. No, not a plan to exploit but rather a consequence of my playing style. Which is to explore as much as possible before I even start gaming. That includes a lot of wilderness traveling (I'm a hunter), and peeking into dungeons I find only to find that I'm having my ass kicked. So when I
do begin the real dungeon crawling and questing because I feel strong and developed enough - now it means that I may actually find creatures there that are still challenging.
Although I prefer some none scaled high level creatures every now and then, they would more be highly suggestive that I stay away. But for the general of creatures, I don't mind them to be "level scaled", because that's just what a GM of flesh and blood would do.
True story from a rolemaster campaign we did ages ago: So we heard a rumor of some sorceress (?) who were keeping slaves to do mine work. Immediately we formed a plan to take her out and grab some good loot. When there, one used a skill to determine her "level" which turned out to be in the 100s, while we were just whimpy lvl 5-35'ish, without a chance going at her without loosing most if not all of our characters. We ended up talking to the guards, and suddenly we found ourselves working for her.
Working FFS! And we all went like, "uhm, guys, how did this happen". In the end, turned out the real loot was obtaining ownership (some steady income) of the mine after we managed to kill her using some real cunning (some landslide spell or something, which took a while to set up) the GM adapted to, and the fame for freeing the slaves using real hired work instead. We had a few fluke streaks combined with some pretty bad rolls for the sorceress, which I believe was "influenced" by the GM as a reward for doing proper role playing and planning. Had we just assaulted her in plain sight - that would not be awarded at all by the GM, and a few characters were lost due to extremely bad decision making on our part.
So, adaptive foes, in an interesting way, for me beats a static world every time you play by a long shot! I'm not saying that Oblivion did it particularly well though
