C'mon, that just sounds like a sore loser :-/ 

SSB3DS overall isnt affecting SSBU sales lifetime, if they are its minor. Like i've been saying this whole time. The gamecould sell 8mil and people will still say 3ds version hurt it. I guess MK7 hurt MK8 sales as well

Allowing players the option of a cheaper way to get their fix will of course hurt sales of the more expensive option.
