The Gold, Silver and Crystal games were some of my favorites. I loved chasing the legendary pokemon around. I always made sure that I had a Master Ball handy to catch them, when I finally ran into one. Right now, I am hunting for Suicune in Leaf Green, and I can't get it to show up.
I am only 1/2 way through Platinum right now. I have put the rest on hold, while I try and add Suicune to my Diamond Game by way of Pal Park.
I too loved Pokemon Yellow. I remember when I accidentally traded away my grandson's walking Pikachu. He was so mad at me.
