That’s the arcade one. The other one is probably season 4, episode 8, “The Vat of Acid Episode”. Morty gets a real-life saving device that allows him to go back to any previous moment in time where he has defined a save. He then falls in love with a girl and lives a long time happily with her, and forgets about the saving device. Eventually, he accidentally goes back to the save point he had made and realized he has lost the relationship with the girl and is again a complete stranger to her. That one hits hard.
It becomes even more impressive when you remember how many amazing games came out in 2023. The Legend of Zelda: Tears of the Kingdom, Super Mario Bros. Wonder, Pikmin 4, Street Fighter 6, Alan Wake 2, The Talos Principle 2, Armored Core 6: Fires of Rubicon, Final Fantasy XVI, Hi-Fi Rush, Marvel’s Spider-Man 2, Lies of P, Pizza Tower, most of these would win GOTY if they had come out this year instead.
