10 Video Games That Broke The Rules
5. Snuck In Credits - Sonic The Hedgehog
Even though Sega's mascot isn't as popular as he once was, 1991's Sonic the Hedgehog is still one of the most celebrated games of all time. Due to the legacy the blue-furred speedster has maintained over the last 30+ years, you'd think working on the original would've been a blast.
But the development on the original Sonic the Hedgehog was heartbreaking according to its creator, Yuji Naka. As was standard policy at the time, the developers weren't allowed to be credited for their work. Naka found this policy so disrespectful, he left Sega of America immediately after the development of Sonic the Hedgehog wrapped.
Similar to Adventure, the legendary programmer defied his employer's wishes and inserted the development team's names in the opening screen before it reads "Sonic Team Presents". The credits are written in black text on a black background, so it's impossible to see them without using a code.
Since Naka flagrantly disobeyed Sega's rules, he could've found himself in legal trouble. But due to Sonic the Hedgehog's astounding success, Sega of America rehired Naka, gave him a promotion, and credited his team in all future projects.
