In recent years, Nintendo has held up a single game as the centrepiece of its E3 showing, be it Zelda: Breath of the Wild, Super Smash Bros. Ultimate, or Super Mario Odyssey. This year, it’s a different brother’s turn.
Introducing Luigi’s Mansion 3 to press ahead of E3, Nintendo of America’s Bill Trinen was keen to point out that while Luigi’s Mansion may not be as obviously well known as those other banner franchises, Nintendo had very high hopes for this third entry in the series. 3DS game Luigi’s Mansion 2 (known as Dark Moon in the US) sold well on 3DS – it shifted some 6m copies – and had appealed both to hardcore Nintendo fans and a strong wider audience.
Also, Trinen said, Nintendo’s own player research showed Luigi was a particularly attractive lead character to a female audience. Take that, Mario.
