Of course I have!
I got into the Tamagochi thing [I had a Rancour], Pokemon [Red, Yellow, Silver, Sapphire, Diamond and, Soul Silver JP ... as of now], Magic the Gathering, Harry Potter [I went to the midnight release of the 5th, 6th and, 7th book as well as the midnight release of the third, fourth, fifth and, sixth movies] and some video game fads as well like Halo and, some of the Zelda games. I was also into Pogs xD
