Things you'd not have believed in the start of the game
With the anniversary coming up, I thought it'd be an interesting question: what would be something you'd not have believed if someone told you at the beginning of the game?
Like how good or bad a certain Pokémon or character would be, any changes, updates that you'd never thought would be added, etc. If you told me we'd be Missing major characters by the 7th anniversary I'd likely not have believed fully for example.
