Pokémon Sword and Shield - There is some good in Sw/Sh, but what's bad is really bad....

Massive QOL Improvements

I actually loved Sun and Moon, unskipable cut-scenes aside, I feel it was the main entry game that pushed the franchise the most: Quality of life improvements such as the removal of HMs, a story that was driven by its characters , and it showed you how they changed, not just told you that they changed, shaked the formula by replacing the gyms with the Alola challenge and most importantly an actually competent difficulty curve that took into account whether you turned off the exp share. The game had flaws, but it was the one who got me back into the fold. Ultra Sun and Ultra Moon in the other hand I did not like because it was the same game, but easier.
