It kind of sounds like you already know which one you want :)
Opinions obviously differ on this, but I’ve not found the Switch exclusives all that compelling. Zelda was a miserable slog, Mario Kart is totally pointless, and while I like Rabbids it’s very hard to play it for more than half an hour in a sitting. It doesn’t help that playing on the PC is just vastly more comfortable with my setup. So the Switch has ended up as a pure travel gadget for me.
