I didn't finish Ultra Sun because it was too soon after and too identical to Sun/Moon. I stopped playing Let's Go because I just wasn't as into it as other Pokemon games. The Kanto experience is just lacking.
That said, I'm pretty excited about SwSh. I know the National 'Dex thing has people in a tissy, but it really wasn't there in SuMo; you could transfer the Pokemon over, but it didn't really count towards the 'Dex, IIRC. So, I don't care about that. I'm not in love with the Dynamax/Gigamax thing, but I do like the Pokemon revealed thus far. So, it'll likely be a yes from me.
