congrats luigi you won your mansion bad news is its full of ghosts...
anyways on with the review yes those awesome ghost portait guys are one of things that make this game awesome they are what people call supporting characters.
theres also the fun in using the poltergeist 3000 sucking those ghost, but it isnt easy, you have to tilt the analog stick in the opposite direction where the ghost is, and struggle trying to catch it till the number reaches 0.
the thing where you have to suck the ghost till it reaches 0 is fast not slow ok ?
plus theres also the atmoshpere i love how it has that quirky spooky feel that makes you wanna be part of its world
and theres secrets, mostly they are money oriented but its worth it, in the end of the game when you collect alot of money you get a way better mansion for luigi :D
so yes this game is a must buy, im not saying "its the best mario game ever" no i like mario but im saying this is "one" of the best "Games" and mario games there is. deffinetly check it out
