I wouldn’t say worst, but maybe greatest difference in expectation vs reality - “My Time at Portia”.
Cutscenes and voice acting were janky. The UI felt like it was originally an MMO and feels odd for a single player game. The gameplay loop felt tedious and seemed to disrespect the player’s time.
Maybe I needed to give it more time, but for a game that I thought had generally good/great reviews, it wasn’t clicking for me.
