Sega has announced that Sonic Frontiers has managed to sell 3.5 million copies since the open-world (or, perhaps more accurately, “open zone”) game launched on November 8, 2022. The new milestone seemingly cements Sonic Frontiers as Sega’s most successful and best-selling 3D Sonic game ever, beating out the previous record holder, Sonic Heroes, which debuted in 2003 for PS2, Xbox, GameCube, and PC and wound up selling around 3.41 million copies, according to figures found in a Sega Sammy presentation from 2007. Sonic Frontiers received a major update in March called the Sights, Sounds, and Speed Update that probably contributed to the game’s continuing success, featuring new challenge modes, a photo mode, and even a jukebox mode that allows players to revisit classic Sonic soundtracks.
From a Steam description:
Worlds are colliding in Sonic the Hedgehog’s newest high-speed adventure! In search of the missing Chaos emeralds, Sonic becomes stranded on an ancient island teeming with unusual creatures. Battle hordes of powerful enemies as you explore a breathtaking world of action, adventure, and mystery. Accelerate to new heights and experience the thrill of high-velocity, open-zone platforming freedom as you race across the five massive Starfall Islands. Jump into adventure, wield the power of the Ancients, and fight to stop these new mysterious foes. Welcome to the evolution of Sonic games!
(I know I said I wouldn't talk about Sonic, but I haven't seen anyone talk about this.)
