Back when I played SMB for the NES I liked Luigi more than Mario. My liking for Luigi died out during Mario Kart 64. I picked him sometimes when I first played it, but then I switched to toad. But I have to say that the only character that I like in the Mario series is Donkey Kong. I know it sounds a little off but it is not. DK is part of the Mario series. That is why he appears in Super Mario Strikers, Super Mario Allstart Baseball, Mario Kart, and of course, Donkey Kong back when Mario was just known as Jumpman.
