I saw listings a listing of someone selling legends za for $12. I was intrigued and looked at their profile and asked them if they could give me the switch 2 version and said yes. I was skeptical of the listing so i moved on. Later, i find out a friend of mine bought from one of these sellers and got an account with Metroid Prime 4 and mg2 for extremely cheap. Im confused on how these people can sell accounts with switch 2 games without the console being able to mod it. Does anyone know how they do it?
