C. Falcon, Young Link, Ganondorf, Samus, Roy, Dr. Mario, Ness. Those are my best fighters. Big Blue, Final Destination, Fountain of Dreams, Green Greens, Mute City, Brinstar Depths, Kingdom II, Onett, and Poke Floats are my favorite stages.
Gosh. Why must I be the only one who likes Big Blue?
Cars are pretty annoying IMO.
Anyway, my favourite characters are Fox, Roy and Luigi. I like how Fox is so complex and that you really need to work with him to get him to do as you command (lol.) I like how you need to be right up close to your opponents with Roy and that his charge attack is a One Hit KO. I like Luigi because he is lethal in the air and his moves are so slick.
My favourite stages are Corneria, Final Destination, Rainbow Cruise, Kirby's Dreamland (N64), Mute City, Hyrule and Pokemon Stadium.
