Luigi's Mansion 2: Dark Moon is one of those brilliant but stubborn 3DS games that rarely comes down in price. You can save yourself a few quid today though as Luigi's Mansion 2 is in stock for £25 on the 3DS.
Still not sure? Then check out Matt's review: "Luigi's Mansion: Dark Moon sees the green sibling joining his brother in the lofty heights of puzzle-platforming excellence, though this is no Mario colour reskin. Instead Next Level have created a game made from Luigi's quivering, cartoonish, paranoid DNA, producing a game so stuffed with charm and character that it could make Scrooge beam."
