But when you're not even compelled to explore the ruins they took the time to develop because you, almost psychically, know exactly what to expect.....the game has far larger problems than its lore retcon.
This is exactly how I felt after a while...
I jumped off the rails pretty quickly. Ignored the main storyline. Just went exploring. And before too long, things started looking
very familiar.
When it came time to do the main storyline I was just about sick of the cookie-cutter dungeons. I didn't want to go through yet another Oblivion tower. I didn't want to go through yet another necromancer's crypt. I didn't want to explore yet another Aleid ruin.
I think, though, that this was exacerbated to some degree by the familiarity of the setting.
Morrowind wasn't amazingly diverse. They had a limited number of tilesets in that game as well. But the setting wasn't the same pseudo-mediaeval thing I've seen in every single swords & sorcery game since the dawn of time. They were at least
different and
interesting tilesets.
The first time I walked into a dwarven ruin in Morrowind, or strolled out into the ashlands, it felt unfamiliar. Like I was going someplace new and interesting - at least the first few times.
The first time I walked into an aleid ruin in Oblivion, or strolled out into oblivion, it felt like I'd been there before. It felt like any other ancient magical ruin in any other fantasy game. It felt like any other hellish setting in any other fantasy game.
