For me it's The Legend of Zelda: Tears of the Kingdom. After Breath of the Wild I was super hyped for a successor. When they announced they were gonna reuse the same exact game world I was a bit worried but thought it could work if they do it well.
Well here we are with like 90% of the content being reused. The gameplay is more interesting than Breath of the Wild and the dungeons are better and so is the story. But my main draw for Breath of the Wild was exploring the world. All this fun is missing in TOTK. The new parts of the world like the sky and underground are pretty bland and not quite as much fun to explore as an entirely new game world would be.
