Morrowind. I’d played it when it came out but didn’t get very far. Tried it again after watching an 8 hour video about it. Focused on speed in my build so I didn’t feel like running at a snail’s pace. Finding the dead people that failed to become Nerevar, giving some guy a book of poetry without a quest telling me to, getting used to the layout of Vivec, actually enjoying the fast travel system, and lots more all added up to such a great experience.
