>>42454692SM has extra story, extra routes, League rematch with new challenger everytime, Guzma conclusion and rematch, also Faba’s, legendary extra mons, backtracking places, battle buffet and the queen, secondary missions through all the region and new mini events that appear in postgame (like visiting the captains and battling them while they show you a part of their lives), the 7 Eevee trainers through the region, the Zygarde cells (boring, but its content after all), the Battle tree, the battle royale...
There’s lots of things to do, it’s not so similar to the the classic Pokémon way of doing content, but it’s a lot of content for a vanilla version.
Being said that, I agree this image is wrong.
