Oh, SURREE, SURE. When Yoshi constantly kills himself so you can get where you want, nobody bats an eye. When Luigi gets ignored, everyone loses their minds.
Reminds me of Paper Mario when you could go to Mario and Luigi's house and read Luigi's diary entries about how jealous he was of Mario and his adventures.
Although Luigi's parents forgot about him and caused him mental distress with their obvious favoritism of Mario, I did make a lot of money from them whenever they forgot they had to get Luigi from the babysitter.
Don't worry, Luigi, I love you.
