Unlike Mario, Sonic’s 3D outings haven’t always delivered, which is one reason why Sonic Colours remains so celebrated. Not only did it nail so many of the series’ base mechanics, it also introduced the Wisps: fantastic beings that bestow Sonic with all manner of cool abilities. Utilising the Wisps’ skills turned Colours into a more puzzle-like experience and also proved that even after 20 years, Sonic still had the power to surprise.
