Other than Sword and Shield (no Switch yet), these are now the only mainline games I've not finished. I played the heck out of Red/Blue back in the day, then didn't touch a Pokemon game until Diamond and Pearl. I couldn't believe how little the game had moved on in almost 10 years and gave up quite early, not touching Pokemon for almost another 10 years. Since 2016 I've played through Leaf Green, Heart Gold, Omega Ruby, White 2, X and Ultra Moon. Ideally I'd have bought a Switch for Christmas but just can't do it with these iteration rumours hanging over it.
