The 20th Zelda game

[el :BeoWolf:]

I don't count Hyrule Warriors since it's a side game, but I do count both Four Swords games and Tri Force Heroes as main series games so that would make Breath of the Wild 19.

BotW is the 19th main series game. Hyrule Warriors is a spin off

I think every Zelda game is special so yes, the 20th game will be very special!
