Stardew Valley. My gf loves it and we have a farm together that we work on sometimes, but the game is too boring for me. I just play it with her sometimes because I know how happy it makes her, it's not a game that I've ever sought out on my own.

Mario Kart. I grew up playing it with my cousins, alongside my copy of CTR. MK is an ok game and it's fun with the right people, but every time I play it I always think to myself "I'd rather be playing CTR right now".
