While Project X Zone 2 may be available for purchase right now, you might be out of luck if you want to purchase the first entry in the series. According to one user, The first Project X Zone has been removed from Nintendo’s 3DS eShop in North America and Europe.
If you downloaded the game before, you could still re-download Project X Zone by going to your list of Re-downloadable Software and going from there. It is not certain why Project X Zone was removed, but chances are that it had to do with licensing issues.
