New Year Mario 2023 is a hypothetical game title. No such game exists for the Nintendo Entertainment System. It's likely a fan-created concept, blending the iconic Mario character with a New Year's theme.  Gameplay could be imagined as a platformer featuring festive decorations and perhaps challenges linked to the New Year celebrations. There is no known company or organizer behind this as it's not an officially produced game.
