Storytelling: Geralt's journey is a masterclass in narrative. The Elder Scrolls games? Bland, generic plots with zero emotional impact.
Witcher 3 was great in spite of its boring main story, saved by it's really great side quests.
At least Skyrim (only one I played), was fantastic at storytelling. All an opinion at the end of the day.
What's the point in asking for other people's thoughts if this is how you respond? Did you just want to tell everyone how great you think the game is?
Edit: That's my bad. Did not realize this sub is called video game arguments, and was created recently by you.
