Today, June 23, marks the 31st anniversary of Sonic the Hedgehog, Sega’s mascot since his first appearance on the Mega Drive / Genesis console back in 1991.Since then we’ve seen the blue blur jump to 3D, become a surprisingly successful movie franchise, and inspire a world tour in the making, where an orchestra will be playing music from past games in the series.However, with the launch of the remastered edition of the first four games, Sonic Origins, Sonic 3 has finally seen some fresh attention too, having been absent on current systems for years.
