"Trying to think of a fun way to play Heartgold and Platinum"

I'm trying to come up with a way to make my pokemon games more interesting or challenging without resorting to doing a Nuzlocke or just beating the game with one pokemon like you see a lot on YouTube now.I was hoping you guys could come up with some ideas or inspiration for my playthrough or maybe I could inspire you with some of the ideas I already have.Some ideas I have for gen 4 are:Shield Wall theme: Only highly defensive or stalling pokemon, like Bastiodon, Shuckle, and Chansey.Wrath theme: only pokemon with abilities and moves based on anger and wrath, like Anger Point, Intimidate, Sheer Force, Frustration, Outrage, Thrash, ect.Nocturnal pokemon only (Youtube idea).Normal Type pokemon only.Starter: Meowth with the ability Technician & the move Payday. Held item: Amulet Coin.Friendship evolution pokemon only (Youtube idea).Fossil pokemon only.Desert pokemon only (YouTube idea).Serpentine pokemon only.HGSS Grass types only, with only berries for consumable and held items.Platinum Steel types only.Platinum Ghost types only.HGSS Fighting types only.HGSS Dark types only. via /r/pokemon https://ift.tt/3AQ9zIv
