I'd say the b&w games were the most boring since it was just "start, battle, do this, battle some team plasma people occasionally, get 8 badges, do glitches, finally get to go into the team base area, battle people, go to N's room and get candy, get to boss room, get legendary from weird orb you picked up, battle two people, CONGRATS YOU BEAT THE GAME!, get volcarona, explore some shit, find seven sages after months, beat the league 19 times with the already op pokemon you had from the last gen, finally get everything in the relic dive place and get disappointed by getting some pocket cash, rek Cynthia, get the other 3 legends you didn't already get, get all of them by IP changing, you did everything." desu, it's not very hard besides the sages and relics.
