If we’re talking PvP, battling has constantly evolved through new abilities, even without gimmicks the way the game is played changed a lot through the years.
In single player they also changed a lot of stuff since gen 4, although the positive changes were mostly in gen 5/6 and the later ones like wild areas and the switch to “””open world””” were… not as well received.
Did those even change anything, actually? I just remember some statues being torn down and the police just doing their business as usual. They also need to be aimed at the correct targets for them to be effective.
