Zelda was indeed released also on the Wii U on the same day, but that's not the point, it's the Switch version which won GOTY and scored 97 on metacritic. And there is no discussion about Smash being a brand new game.
What is the difference between Wii U and Switch versions? For sure resolution, what else? I have no clue why you are acting like Zelda Wii U never happened.
Smash, no difference for me, OK it is a brand new game, just dont come to Polish Nintendo forums with that statement :)
If we count the brand new exclusives in PS4 2 years with Switch 2 years, the brand new ones, it is BloodBorne vs Odyssye and Smash, if count with others, it is Journey,TlouR,BB againts BotW,Odyssey,Bayo,MK9 and Smash, so 3 vs 5.
Nothing earthshattering for my money.
