I can relate to this. I was born in 1990 so I'm the perfect age to be a "Pokemon guy" but I never had a Gameboy or Nintendo system growing up. My first gaming system was my dad's PC and then a PlayStation I picked up cheap on holiday in 2001.
I completely skipped the whole Pokemon thing growing up. I finally gave Pokemon Leaf Green/Fire Red a go a few years ago and actually rather enjoyed them, but every new game released introduces tons of new Pokemon and types and I just can't keep up. There's too many other universes filling my brain; Star Wars, Tolkien, A Song of Ice and Fire, Mass Effect, The Elder Scrolls, Fallout, etc
