This is such a hard question for me! I feel like my answer changes constantly. All in all, it's gotta be a tie between the Witcher 3 and The Legend of Zelda: Twilight Princess. The Witcher 3 had so much effort put into it. The story was incredible, the characters were lovable, the voice acting was top notch, the graphics were beautiful, and the dlc was handled perfectly. The Legend of Zelda:TP on the other hand is my most nostalgic game. I sunk so many hours into that game. The dungeons were awesome, the bosses were brilliantly designed, and the main bad guy was quite intimidating. On top of that, the game can be pretty creepy when it wants to be.
