While Mario gets zillions of games to himself every year, it's not often that Luigi gets his own lead, unless you count 1993's MARIO IS MISSING on the SNES.
In this cool little game, Luigi goes Ghostbusting in a haunted mansion (one of those Scooby-Doo types) that he has mysteriously won in a competition he didn't even enter. The mansion is crawling with spooks of all kinds but Luigi get's help from a crackpot inventor living nearby. Now armed with a special vacuum cleaner, Luigi must clear every room in the mansion and find his missing brother, who has apparently vanished inside.
The gameplay is simple and very easy to get the hang of. Some of the rooms you clean up require some extra investigation and puzzle solving so be sure to check everything (I though the piano room was a cool puzzle to solve) and use your Gameboy Horror to have a good look round.
The graphics in Luigi's Mansion may not be up to the standard of Super Mario Sunshine but they're still very, very smooth and look amazing. Some of the SFX look highly realistic and there's no loading times at all between scenes. The music sounds like it's been done on a Commodore 64 and doesn't sound all that great but it's a cute little theme and I thought it was very funny when Luigi would whistle it whenever it wasn't playing.
The mansion itself isn't that big and you'll finish the game in about a week, but when you have this much fun playing it is still worthwhile.
