Initially, I thought Luigi's Mansion sales were for up to today / last week, but reading the PR better, it seems those 415k could be just March. In the case...holy crap, a 50k digital debut?!?
On the 3DS digital eShop All-Time chart, Luigi's Mansion is #14. FE with 80K digital sales dropped down to #7.
U.S. 3DS All-Time Download-only Sales (until April 18)
Note: Bundled/Ambassador games are not included. Basically just anything you had to click on 'purchase' button to get that at some point in its life cost money.
