I started off playing Pokemon Blue on my mom's old original gameboy, and then I got pokemon red for my birthday not too long after. I bought myself a gameboy color, and the rest is history lol
Yellow! my friend got blue so I really wanted to get a pokemon game so my dad got me any pokemon game which turned out to be yellow. Suffice to say that I enjoyed it so much that I got every pokemon to level 100. That was my childhood right there.
Mine was Pokemon Silver when I was about 10yo. I remember playing it on my GBA SP (which I still have!) and boy, it was so fun!
Playing the remake made me enjoy everything once again with revamped graphics
