So what about Pokémon made you like it and gravitate towards it? What about this series ignited that spark of joy when you were just a wee lad? It's fair if you can't pinpoint any direct thing but even a general feeling is enough.
I remember when I got Gold and I just liked how whimsical the setting felt while still feeling grounded if that makes any sense. I also remember feeling a real sense of accomplishment whenever I overcame an obstacle that I was having trouble with, I remember feeling so proud of myself when I finally beat Morty after I wasn't able to get past his Gengar for what felt like forever.
Anyway what was it that hooked you in?
