Sonic the Hedgehog by SEGA is one of the most influential franchises in video games. While Nintendo is well known for Super Mario, SEGA is well known for Sonic. The blue hedgehog became the mascot of the company and a multi-billion dollar franchise. The series also spawned two live-action movies, with a tv show and a third movie in the works at Paramount.
It seems the franchise also contributed to the sales for the Japanese publisher. Earlier, the company disclosed numbers for their franchise and how well they performed. SEGA published updated sales for the Sonic franchise in it, claiming that the series has cleared 1.5 billion units (via VGC).
The numbers showcased include premium game sales and downloads of various Sonic free-to-play titles released. While the franchise was at its peak in the 90s, the mobile game market helped it reach new heights.
In 2013, SEGA launched Sonic Dash, Sonic Runners and numerous other free-to-play titles. These games featured microtransactions. Taking in numerous sequels over the years and free-to-play games, we can conclude that much of this number consists of the money made from F2P mobile games.
As of now, the Japanese developer is preparing to launch the next game in the long-running franchise for PC and Consoles. Named Sonic Frontiers, it will feature the game’s first fully open world, where players can discover and play as their favourite hedgehog.
