Pressing a preferred combination of buttons when trying to catch a Pokemon (tapping A over and over, B + Down while the ball is in the air, holding B every time the Pokeball shakes, etc.)
Saving right in the center of the Pokeball on the floor of the Pokemon Center
Saving again, just to be sure
Rarely save with the volume turned down, wait for the little “ding”
Buying items in a specific number and ensuring that the amount NEVER changes
Compulsively searching each and every trash can for an item
The strange tendency for one or two Pokemon to be 5+ levels higher than the rest of your time
Giving Pokemon nicknames that have the first letter capitalized and the rest lower-cased
Generally keeping the volume low unless saving or a Pokemon is evolving
When one of your Pokemon is confused you repeatedly tap A while telling the Pokemon you believe in it
Keep Starter Pokemon on team based not on how good it is but on a special bond with it i.e. it becomes your “bro”
Insult NPC opponent/opponent’s Pokemon when they get lucky or knock out your Pokemon
Have a system for categorizing your PC box (by type, favourites, colour, etc.)
