Mighty Gunvolt is free though. I could see the milking argument if they were charging full price for it, but it's just a fun little side game meant to bring together comcept characters. It's basically the "Mega Man a" of both Mighty No. 9 and Gunvolt, a fun little retro diversion to enjoy.
Alongside another game that nobody really would factor into this crossover (That being GalGun of course.)
Anyway, Backer reward surveys came out (For physical items.) Turns out the Physical copy of the game is just a box and manual, if somebody actually wanted a physical USB Dongle/disc they have to pay extra (Its like $36 extra for a dongle shaped like an NES/Famicom cart.)
Oh well, no point since the game's digital anyway. Just the box is fine, still a bit of a disappointment. Japanese box for me though.
