You are right on the money my friend. Then I grew up and I realized that I needed to train other types of Pokemon to stand a chance against Blue. --- I just cant sit any other way than this. If I sit the way other people do, my reasoning ability drops by 40%.
Early game I used Butterfree and Pikachu, both would be benched by the end though
You just reminded me how I used to call boxing "benching" and my team was my "belt." I think I'm going back to that right now.
But yeah, I'd keep Butterfree/Beedrill for a while, but they almost always got replaced. I never took a Pikachu through the game outside of Yellow. I always caught my Pidgey before Viridian. --- I like Monster Rancher.
By the time you played Yellow, hopefully you had already played Red or Blue at least once and didn't care to use Pidgey again. And you were given Squirtle, Charmander, Bulbasaur, Pikachu, and Eevee which all kids thought were SUPER AWESOME AND COOL at that time... I highly doubt you would use PIDGEY as your ONE other team member... --- "Earth is a silly place. Half the world has no clean water. And the other half has so much, they poo in it."
Nahhh, I used a team of Venusaur/Wiggly/Hypno/Farfetch'd/Seadra/Aerodactyl on my first playthrough on my Red cartridge. Still have the file to this day. In fact, the only one you listed that I've actually used in RBY is Pidgeot on Blue.
