Life can't be easy for Luigi, sulking around in big brother Mario's shadow. He's like Beyonce's unfortunate sister Solange Knowles, but with a moustache. Launching the Nintendo GameCube without Mario was considered hardware suicide by many, and Luigi's Ghostbusters-esque adventure was thought of as a meagre substitute, but Luigi's Mansion definitely deserved far more credit than it got at the time. Critics called it formulaic and uninspired. A lot of them suggested that you give it a miss and wait for a "proper" Mario game instead. But Luigi held his own - the beautifully structured ghost-hunting and exploration was bathed in cute yet creepy atmosphere. The result? Miyamato's supporters bought it in droves, despite review scores below what we expect from a Mario-related launch title. Industry voices may have underrated the charm of this subdued classic, but it earned its respect by giving us a distilled action-adventure which captivated gamers from start to finish.
