BotW I'm already getting on Switch so I'm willing to pass on it for the Switch. Mario Kart 8 Deluxe doesn't hold much appeal to me since I already have it on Wii U. While a different battle mode is nice, my brother and I actually found enjoyment in the battle mode of MK8 and didn't mind it that much although smaller contained courses would be better. Never got into Splatoon on Wii U and not interested in the sequel at the moment either.
To be clear, Mario Odyssey is the only game I see myself being willing to buy at full price. All other games I'd be willing to wait for a deal at some point. 1,2,Switch is the most iffy but for the right price, yes, I'd positively buy it. Snipperclips seems to be getting the most hype building for it and it is one of the most intriguing titles. Arms has sold me the more I've seen of it. Still have to play the first XC to be properly hyped for the sequel but the time spent with XCX buts me squarely in the buy now play later category anyways. I like Hyrule Warriors despite the repetition that can occur. However, I think Fire Emblem makes a much better fit and despite not playing an FE game yet, I'd be done for this title due to my Hyrule Warriors experience. And I collect Pokémon games. I don't play 'em but I've got them all except Sun and Moon currently.
