Finally arrived! I actually thought it would take longer, but it seems that the tracking page just wasn't updating. Anyways, finally got it!
Glad that the site I ordered from was able to ship the game immediately after the weekends without lack of stock. (I did pre-order though)
Of course, I have already finished transferring all data to the New 3DS.
Also, it is great to be able to use Up/Down moves in Super Smash Bros now. (Old system's D-Stick was a bit overused).
