I am so excited for this... No, seriously, I'll even give you a bit of background if you care:
I first got Luigi's Mansion back in 2003, and I beat it twice during the summer of 2003. After that, for some reason my 2003 summer had become the most nostalgic part of my entire life.
So, anyway, I had beaten the game a few times after that, and in the year 2008, I went backed and played all the games that I had played back then, like LM and Smash Bros. Melee. But with Luigi's Mansion, I had played and beaten it ALMOST every single weekend of that year. I would have little "nostalgia nights" every weekend, pretty much, and to this day, I still have them and beat Luigi's Mansion every time.
Although I don't play it as much anymore, it still has a special place in my heart, and you can probably imagine how many times I have beaten it. Too bad I lost count lol (memory card wiped out)
So, anyway, sorry if I rambled there, but it was basically building up to the fact that I have always loved this game, and the fact that a sequel is coming... Oh god oh man, you have not the slightest first clue how excited I am for this.
The only thing I disliked from the trailer was the slowness when sucking up ghosts, BUT I DO REALIZE it's going to be fixed. I liked the music, the look of the new ghosts, and pretty much everything.
I may just be biased, though. :D
