Emerald's my main game, but of FR/LG, my Leaf Green would be my 'main' one I guess. It was the first one I got, and I loved it so much that I beat it in five days. >_> I tried to go slow, but I couldn't help it, lol.
My Leaf Green still has its original file, while my Fire Red doesn't. I restared it because I wanted to play as a guy, and my LG was too "Precious" to me to erase, probably because I got it first, and I have more pokemon on it.
