i think luigi cause if you guys remember on the ds super mario, you had to unlock luigi. then again you also had to unlock mario, but mario came first didnt he?
Only because Mario came first do people know him more and instictivly like him better. The first attempt to make a plumber failed, but gratz Nintendo, you got it right the second time! Anyway, Mario goes to the wrong castle like 8 castles before he finds Peach. Luigi goes to the right mansion the first time and saves Mario's sorry hide. The first time.
Luigi. He can jump higher, has better moves on all SSB games, shoots better fireballs, has a hotter girlfriend, and has a cooler name.
