This is most AC games for me but Black Flag is the best example. Loved that game and really enjoyed just doing pirate stuff. I did progress in the main story but not sure how close I was to finishing. If I ever play it again I will do the exact same… everything outside of the main story was the best part!
I probably had 20 hours into this one when I just said, nah I’m good here. I knew I didn’t have it in me to sink the time needed.
