Yuji Naka, co-creator of the legendary Sonic the Hedgehog series, has been found guilty and sentenced for insider trading. After joining Sega in 1984, Naka made a name for himself for his work on titles like Phantasy Star 2, Nights into Dreams, and Burning Rangers - but his most noteworthy contribution to gaming is his part in creating the Blue Blur. Naka remained a part of Sega until 2006, when he left to create his own development studio Prope. From there, he would join Square Enix to direct Balan Wonderworld - a colorful platformer that was panned by critics and met with poor sales in 2021.
