Sonic Frontiers is officially the best-selling 3D Sonic game of all time, smashing through a previous milestone set by one of the older titles.

What makes this milestone so important is that Sonic Heroes, the first proper multi-platform 3D Sonic the Hedgehog game was known for selling 3.41 million copies at the end of 2007. This effectively made it the best-selling 3D title the franchise has under its belt. Despite the success of Sonic Generations and the Wii-exclusive Sonic Colors, Heroes held onto its claim to fame for 16 years. Now, Sonic Frontiers has broken its milestone in record time, making Heroes the second best-selling 3D title after a long run at the top.
