Super Mario Run: Nintendo shares plunge amid bad reviews, reducing company's value by $2 billion

Nintendo has launched Super Mario Run, its first game for iOS, and found itself worth $2 billion less than when it started. The game received huge amounts of hype for its combination of nostalgia and excitement, and as a signal that Nintendo might look to move more of its games off its less popular consoles. But it has already been hit by some backlash, over its high price and a mode that means it will only work if players have an internet connection. Those concerns appear to have dragged down Nintendo's share price, which fell by about 5 per cent in the wake of the release. That meant that the value of the company dropped by around $2 billion.
