Yes, mostly Wes Johnson with a bit of a very annoyed Sean Bean.
But I have a soft spot for the over the top Sheogorath, the unnecessarily aggressive guard shouts and the calm voice of the Khajiit women.
Some of the other few voices I can’t stand, especially the blacksmith of Chorrol (“A pleeeeasure to serve you”).
In Morrowind I like the story and the music. But as I explored the battle mechanics, I couldn’t stand the randomness.
Also in a later retries after Oblivion and Skyrim I missed the real talking more than the graphics enhancements.
A bit unfair, I know. Maybe I’m not that game connoisseur myself.
I used to be a Dragonborn like you, but then I got a fire arrow to my dedicated graphics card.
Now nothing newer than Oblivion will ever run on that machine.
Found the interview about voicing Oblivion again:
