Then your boyfriend either works at Natsume, or you are mistaken. www.natsume.com click on support. You will see a consumer phone line. Give them a call and ask them what the release date is for the game. I assure you the nice guy on the phone will tell you More Friends of Mineral Town isn't scheduled for release till July 12th.
The game hasn't even gone gold yet, that means this game isn't even finished being translated/reprogrammed/debugged.
most likely your bff probably ordered it online...you know even though something isn't released yet...sometimes the manufacturing company sells the products already made online only...yeah I saw an Animal Crossing DS game and it's for US already selling online and the release date is late november..of course the thing is costs big bucks since it's not officially released...
