You win the USA Power ball for $1,000,000,000 what do you buy first?

I would buy a Nintendo Switch and a copy of Breath of the Wild. I've been really keen to try it, seeing how greatly it was reviewed, but I just can't justify paying $500 just to play a game :/. I'd probably buy a whole lot of games actually, although I've got a lot of games that I got for free (promotions, etc.) that I haven't been bothered to play yet.
