I don’t think it was my first memory of Pokemon as the TCG was already out and just like every other elementary school kid I was into it, but it was my most memorable.
My oldest brother said he would buy me up a copy of Pokemon if I could pay for half the price. I remember dragging the lawnmower behind me as I went door to door asking the neighbors if I could mow their lawn for a couple of bucks so I could buy Pokemon. When I got enough money to give to my brother, he gave me a choice of Blue or Red and I choose Red keeping Blue for himself. I would then choose Bulbasaur for my first ever digital Pokemon.
On a side note he would later give the Blue version to my younger brother after he bought the Gameboy Color Pokemon Yellow Special Edition.
