Sonic Boom is the worst-performing Sonic title to date, SEGA has revealed.

In the company’s latest holdings report, Sonic Boom: Rise of Lyric and Sonic Boom: Shattered Crystal have sold-through just 490,000 copies to consumers worldwide.To put this in perspective, in the year ending March 31, 2014, Sonic Lost World managed to shift some 710,000 copies. Before that, Sonic Generations sold 1,850 000, and in 2012, Sonic & All-Star Racing Transformed pulled off 1,360,000 copies worldwide.It’s not all bad news, mind. SEGA also released the sales figures for Alien: Isolation, which at the end of 2014, had sold some 1,760,000 copies. Considering the company only just announced it'd passed the 1 million mark , it seems that was either a delayed message or sales have picked up.What’s next for SEGA in 2015? After offering voluntary retirement to 300 employees , and relocating its offices, the company plans to focus heavily in the digital sector. Speaking about the voluntary retirement and digital future, SEGA said the following:“Voluntary retirement will be solicited in the aforementioned businesses to be withdrawn or consolidated and downsized,” a statment read , “while at the same time personnel will be repositioned in Digital Games and growth areas of Group mainly as development personnel, in order to establish a structure which can constantly generate profits.
