Built my first ever PC - What single game should I buy?

I've been occasionally gaming on poor laptops for 20 years, and during that time, I fell in love with only a few titles: Oblivion, Skyrim, and Battlefield 3.

Now that I finally have a powerful gaming PC, I'm looking for an AAA game to play occasionally after work. I need something that's not too challenging, as I want to unwind after a long day. Elden Ring might be too stressful for that.

What single game would you suggest that could match the enjoyment I found in Battlefield 3, Oblivion, and Skyrim?
