None for me. Would've been an even funnier thread if Nintendo 64 was launching
"Excluding Mario, what game makes N64 worth buying at launch?"
*crickets*
But yeah, if you have a Wii U, don't buy a Switch for Breath of the Wild, Mario Kart 8 Deluxe, or Splatoon 2. Wait until Mario Odyssey.
If you
don't have a Wii U, those games are masterworks that are absolutely deserving of your time and money (okay, I don't have a time machine in Splatoon 2's case, but if it's as iterative a sequel as it looks to be so far, I can confidently state that it's worth your time and money). Once at least three games that you want for the system and can't find anywhere else are out, pick it up. Same as any other game console in this day and age.
