Mario & Yoshi (Game Boy/NES 1991)
Box art suggests: Another classic platformer featuring the timeless partnership of two of Nintendo's best-loved characters with all their classic foes making an appearance.
The reality: It's a puzzle game. The only 'platforms' are plates that Mario switches round to stack up themed blocks. While Yoshi is pictured at the side. For some reason. Can we have our money back, please?
Above: Wouldn't anyone logically assume this should be a platformer?
