Open world RPG game?

Hi, Long time Assassin's creed here, played the series only out of loyalty to the franchise. I stopped having fun playing it since black flag.

I recently played Ghost of Tsushima and for the first time in about 6 years (since RDR2) I had that feeling that I don't want to stop playing. I even made side quests after the main story is over, something that I NEVER did before.

Can you please suggest similar games to bring back my passion into gaming?
