Will this be the only release of the game or just the first shipped? I'm glad I resisted the urge to pick it up digitally. eBay can be really annoying with the flood of empty case and art listings for the eShop games, this will just help get rid of a small amount of them!
No. The news out maybe 2 days ago a full US release is coming because Nicalis picked it up. Going by their other stuff like Tiny Barbarian DX, Isaac, and Cave Story is should probably be a $30-40 release with the usual extras in the case.
As far as Mario goes, only up to the break between the beach and snow areas as I'm going slow and playing it in a few hour bursts here and there so it lasts. I really should try and take down the ending at the least as November has Doom, Skyrim, Axiom Verge, and RIME all showing up. And so far it feels as amazing as Mario 64 did when it first came out which the others since have in a little bit to more lacked in some way or the other. I really don't have any complaints as I'm more surprised how much there is going on and to go back to.
