My best friend and I have been playing pokemon for years now, we have recently decided to try a nuzlocke run for fun. Now my only issue is this guy zooms through games, he is just naturally fast and easily overlevels everything compared to me. I want to make sure it is a challenge for him, so my question is what is the hardest pokemon game? Any game is fine to pick outside of Kanto based games because we just finished playing FRLG.
