Red and Blue We got them around the time they came out, maybe a few months to a year or two after they came out we bought them, no clue when exactly.
i ahd blue then i dident play another Poke game untill platinum. but now i have gone back and bought and finished every one..
I bought silver for the gameboy color used it had espeon and it was amazing until i restarted it and made a god like Ampharos which owned everything with thunder punch
gotta be red/blue/yellow. if you dont' start there, you can't truly appreciate how far pokemon has come. silver was my favorite tho. lets see if SoulSilver can top it
i started with yellow got from friend, thought it was odd how that one was only one with a pokemon to follo you
got gold first and got full pokedex XD no celebi ): then i think i either found or bought blue then played leafgreen....so 2nd gen
