Duck Hunt Dog is kind of the worst and best addition. Worst in that, really? Duck Hunt Dog? Aren't we seriously scraping the bottom of the barrel here? Is there no one else of substance to add in all of Nintendo and even just gaming that Nintendo can manage to have access to or work out a deal with like Mega Man, Pac-Man, or Sonic?
But it's also great cause he's a total send up to the NES Zapper games and could be generally entertaining to play lol
I think for the next Smash or as DLC, they need to add Shovel Knight lol
