I'm planning on getting a preowned New 3ds Xl from someone and the listing says it has games downloaded onto the system. I have my own 3DS (the older version) and I created a gamer ID on it to help get in touch with my friends in order to play on a game together even when we're far away. I'm worried the games would be affected somehow if I were to input my gamer ID into the system. I'm just a dummy who has no idea how this stuff works so I would appreciate it if someone were to help me with my issue. I haven't found any other person asking this so I decided to reach out for myself. Thanks.
