I'm currently playing the newly released Luigi's Mansion Dark Moon. So far it's nowhere near as good as the original but it's still fun nonetheless. I'm in the second mansion with a play time of maybe 5, 6, 7 hours. I've collected everything up to this point, Boo's, Gems and beaten the 1st bonus mission. The 1st mansion for me was pretty decent, the only hard point being the 1st boss. My rating for the first mansion would be a 4/5 for the simple fact that it was the first mansion, a tutorial mansion you could call it. Being the first mansion in the game it still had me in awe all the interesting places to explore in, and the money is fun to find. I'll post my next update when I progress further into the game.
