Just finished Luigi's Mansion: Dark Moon.
It's a fairly good game, it had interesting environments like the abandoned clock factory, that freaky ass museum mansion etc. I miss the free roaming the first game had though. The only problem I had was with the 4th boss. What the hell was Nintendo thinking? You don't make a game all about catching ghosts with a vaccuum and then suddenly change the gameplay to a physics based shooter, especially one that isn't forgiving in the slightest.
