My favorite touch about Luigi's humming is that the lower his health gets the shakier it actually is.
He goes from reasonably composed to "Sounds like the slightest noise is going to give him a heart attack."

Poor Luigi. Even his own game is categorized as a "Mario game."

I'm absolute favorite feature of the game along with the humming is the "Mario" button.  I mashed the hell out of that thing through the whole game as if I thought MAYBE just MAYBE he might hear me.  Mario?  MaaaaarrrriooooooOOO!?

You forgot one other character trait for Luigi.
It's that he's filthy stinking rich.

Yeah, everyone using the lighting glitch to make theories about Luigi hanging himself always bugged me. I mean, the table's shadow is hovering too. Did it hang itself? Did it not like its life? Could it not pay rent in time? Did it go through a divorce, and lose custody of its kids? That's the real mystery about the glitch.

"Speak not my name for I am TaBOO"

(scans lion statue) "This is the kind of thing I would put in the bathroom."

"When there's something strange , in the neighborhood , who you gonna call , LUIGI "!!!!

Maybe it’s just me but I think Luigi’s Mansion uses it’s short length to it’s advantage, you can beat the game over and over to see if you can beat your best score in total treasure collected! At that point it almost becomes like an arcade game... at least that’s how I’ve always seen it.

Funny note about the birds in the intro:
The birds aren't the only thing modelled for that one shot. The tree they're on is not only modelled just for that shot, it's not even attached to the ground!

With Luigi's Mansion and Survival Horror: I would actually argue it essentially is a survival horror game, just a very defanged one. It has the basic features of one, and even the tone is somewhat spooky.
Actually, one thing I'd praise the game for is getting just the right amount of spooky for kids (at least, saying it from my experience playing the game when I was young). It has a gloomy and kind of creepy atmosphere, but not enough to be truly uncomfortable. One thing I wanna give credit to in particular is the ghost's appearance and the sounds they make. They're kind of cute, but there is in fact something vaguely predatory-even sadistic-about them. The sounds they make also reinforce this, sounding both otherworldly and, again, predatory.

Unless, of course, you read "Born a ghost" as "Was stillborn"...

Luigi's mansion dark moon was fun, but honestly the fact that they cut down the ghost variety and replaced with those generic ghosts that possess objects (its a good concept and they did some good things with it, but having ALL bosses be them isn't very interesting). It does have a lot of cool puzzles and new mechanics, and the idea of going to various mansions is really cool too, but it feels like overall it lost some of its character and atmosphere in exchange of more polished gameplay. I do like king boo's new design, really sets him apart from the pack.
Overall, dark moon's gameplay is sharper, but i'd still say that the original luigi's mansion is more fun to play. Though i'd buy a luigi's mansion 3 in a goddamn heartbeat if they made one. They could easily mix the 'big open-ish mansion' from 1 with dark moon's multiple mansions, like, make the new area be a whole neighborhood, or a small town, even!
I do hold a whole lot of nostalgia for luigi's mansion 1 (after all, it was my first gamecube game),  and one weird but very funny memory i have of it is that my grandmother always found the way you could make luigi keep calling for mario very funny.

You can do horror games all year for all that I care.

I remember playing this game as a kid, and legit being freaked out by some things like the butler. As a kid, I thought it was chasing me down, and I left that hallway and hid upstairs as fast as I could. I also being creeped out by all the bosses, and mashing the call Mario button. The thing that I realized about dark moon is it doesn't have nearly as much of a creepy vibe, but more of a cartoony feeling.

It is actually not the first time that Luigi had a personality, in Paper Mario you can read his diary and know what he is thinkimg about Mario's adventure and stuff

I've always referred to Luigi's Mansion as "Silent Hill for kids." Glad to see I'm not the only one who made this connection.

I loved Luigi's Mansion because it was so different for any Mario game before, also it fleshed out Luigi's personality too.
I was so happy when they annouced the second game and when i played, Luigi's Mansion 2 became one of my favorite games of all time, i know it's not one of the best games of all time but the games alone are so charming and unique that i cant look over them.

15:24 Great, now I can't shake the picture of a whole orchestra band following Mario in a Koopa clown car out of my head.
