Was Morrowind for me. Climbing out of that prison galley to find myself in that foggy alien swamp with the rumbling groans and sorrowful cries of the nearby silt strider. Realizing shortly after that if I could see it lying around, it had value, and I could pick it up and keep it or even sell it if I wanted to. The world felt so mysterious and hostile. I had no idea what strange sights lurked out in the mist. That brown, dusty, ancient world always felt like I was cracking open a lost tome rich with lost customs and mystery.
