All right, well, I'm almost finished with Luigi's Mansion 2, and, anyone who has played the first game, should recall how horrifying it was to have all of the ghosts chase you around the mansion as a result of a power outage. Well, in Luigi's Mansion 2, you end up with a similar experience. To say the least, a portal opens, and, a bunch of ghosts escape it, and, you have to catch them again. Unlike the power outage in the first game, this isn't the result of a power outage, and, ghosts are not everywhere. Instead, the ghosts are in specific parts of the mansion, and, you're on a time limit. I remember that the beta version of Luigi's Mansion had you on a time limit to save Mario, so, perhaps this was Nintendo's way of resurrecting an aspect they wanted, but, for whatever reason, didn't include.
