I think we should give Luigi a better stage other than Mushroom Kingdom 2. I think fighting on the rooftop of the mansion would be excellent. And at times, King Boo can make Cameo appearances and launch a slew of Ghosts to try to attack the characters, but you can just knock them back. I'm also not saying this stage should symbolize Luigi as just a "Vacuum-Wielding Brother", but I think it is the stage that can represents him the most. That's just in my opinion, though.
