I've only played this for about 5 hours after buying it new. I'm selling it because I feel pressured by my backlog with the release of a new game. I only used it on an official Switch, but there are contact marks on the chip (see photo 5). I've just confirmed it works on Switch 2. It plays without any problems. The items included are everything in the photos. --- A new Pokémon experience that fuses action and RPG elements. - Title: Pokémon Legends: Arceus - Genre: Action RPG - Platform: Nintendo Switch - CERO: A - Online Features: Yes Thank you for looking.
