Got blue version around when it came out for my big old grey gameboy. Was the greatest thing I've ever received and Pokemon may be the only thing thats stuck with me this long.
My fondest memory is between: not knowing the trade evolution thing and training my Kadabra up to level 96 legit and asking my mom why it wouldn't evolve.
Or finally beating the Elite Four/Champion and reaching the HoF that so many talked about. Had Blastoise, Dragonite, Pinsir, Beedrill, Dugtrio, Dewgong as my first ever HoF team.
