What are some things you’ve never done playing Skyrim, even after hundreds of hours?

For starters, this is my first time actually traveling with Delphine to Kynesgrove. Usually I just tell her “I’ll meet you at Kynesgrove” but I wanted to see what would happen. She has some unique dialogue which is cool.

Past threads always have someone saying “I never finished the main quest” which is common for some reason.
