Honestly kind of underwhelming but I was specifically excited for two things:
1. Both Kirby games look awesome. I might be getting a Switch sooner than I thought, since Star Allies is coming in Spring, I honestly thought that would be here by Summer at the earliest. Definitely excited for Battle Royale too, though I'm not really planning on getting it right at launch since it looks to be a more experimental title than a traditional one.
I am a bit underwhelmed compared to my hype for Planet Robobot, but considering how much Kirby stuff we've been getting over the past year it's hard for me to be super excited, especially since I thought Triple Deluxe was a bit underwhelming and skipped Rainbow Curse at the time Planet Robobot was announced. That being said though more Kirby is never a bad thing!
2. Holy crap the Switch has so much third party support. I may be speaking too soon, but man they're really stepping up their game with third parties. I was already surprised enough that LA Noire was announced for it last week, but I never would have expected Doom and Wolfenstein II to come to the system.
