Though it doesn't add anything new, this portable version of the classic Nintendo game is still frighteningly good. Originally released on the GameCube in 2001, Luigi's Mansion has Mario's twin brother cleaning up an old house. But he's not busting dust bunnies and cobwebs; he's eliminating the ghosts that are squatting there, and possibly hiding Mario. To do this, Luigi first has to stun these spirits with his flashlight, and then catch them with the Poltergust 3000, which is basically cross between a vacuum cleaner and a proton pack from Ghostbusters. He even gets to team up with a double who looks and acts just like Luigi (if he was made of Jell-O, that is). There's also, as with so many of his brother's adventures, tons of puzzle solving, exploration, gathering gold coins, and having to figure out how to defeat the larger enemies before trying over and over to actually do it.
As for this new edition, apart from being able to see things in three dimensions, and use the lower screen of the 3DS as a map, it also adds a mode called "Gallery Battle" where you can battle the game's bosses again and again in hopes of beating your best score. Otherwise, this is a faithful rendition of an older game, which holds up very well, for the most part. It's hard not to think that this wouldn't have worked a lot better on the Switch, with a controller that has two thumbsticks. It's also kind of a bummer than it doesn't add any new gameplay mechanics, maybe in an alternate mode, or take advantage of the 3DS' 3D visuals with a unique gameplay twist. But these concerns aside, Luigi's Mansion is still as fun, clever, and as challenging as it was when it was originally released in 2001.
