The characters would all be from the world they start in. Fighters/mages/archers from Fire Emblem, trainers from Pokemon, Bounty Hunters or Space Pirates from Metriod, Toads/Yoshis/Koopas from Mario, Waddle Dee or the like from Kirby (perhaps Kirby not so great idea), Townsfolk or other adventurous kids/adults from Zelda, could all be part of the choices.
Me? I would choose a Fire Emblem Swordsman with the possible option of being a flying character. I would strive to depose the rotten king/queen and lift up the rightful ruler. Second choice would be a Bounty Hunter or Phazon Boosted Space Pirate with a Metriod mount, that way I can suck life energy from my enemies while riding. I would try to become the most powerful I can be and try to take (Dark) Samus out.
