The first character that I ever picked was Link back in Smash 64. He quickly became my favorite character and my definite main. However, Melee was released and.... I still picked Link first. Not on purpose, it just happened as I was excited to try my main out in Melee. He is my most played character in those games, I had something like 78,300 KOs with Link before I reset my file. After that, I still played Link daily, the number never really got that impressive again (as I reset my file another dozen or so times), but I neglected my other mains (Zelda/Sheik, Ganon, Captain Falcon, Jigglypuff and Mewtwo).
So now for the question. I got Brawl, for months I was contemplating who I would try first. I decided that I should maintain my tradition and choose Link first (this time was the only time that it was my intent). Yeah, I have ****ing hated him ever since and began maining Toon Link instead.
