If we're talking about open-ended games, it would be Stardew Valley with Animal Crossing: New Horizons as a close runner-up. I've been playing Stardew Valley since 2018 and played Animal Crossing since launch.
If we're talking about games I played for the first time in 2021 and have a clear story/quest, it's gotta be Persona 5 Royal. I started Persona this year with Persona 4 Golden, then P5R, then Strikers. Royal is the best of the bunch.
