- Aurora Beam would be renamed, or there would be a Light type in which would be Aurora Beam.
- Pokémon academies would be better.
- Nintendo guidebooks would be at least completely accurate.
- Types would be more balanced, and maybe there wouldn't be any 4× weaknesses or resistances.

The remaining HM moves would become TMs, and Surf would be the only unforgettable one. Surfing would allow the player to cross waterfalls.

- In Generation V, people's eyes would not disappear, Pokémon's back sprites would be less pixelated, and entering buildings would take less time.
- Event Pokémon (such as level 100 Arceus from the Pokémon Global Link) would be unavailable for delivery until the player had enough Badges.
- In general, all Pokémon would be equally viable at all levels (excluding Smeargle, legendary Pokémon, and evolutionary stone/trade/friendship evolvers).
