So true. Each generation is a pleasent experience (althoug Ruby/Sapphire really didn't appeal much to me) but NOTHING compared to the first experience. I remember being 12 and when I discovered DIG I was like "Wow, you can't attack me one turn. Then, I attack you. Awesome".
Then, the first time ever to ride the bike (insert bike tune), each Rival appearance, and what's this pokemon at the end of Cerulean Cave??
