In the game development process, it is common for programmers to change a number of things between the prototype versions and the final editions. This is the case with Sonic the Hedgehog for Mega Drive, whose full gameplay has been released on the network.
The video in question appears on the network 30 years after the franchise arrived on Sega’s 16-bit console. The first noticeable change is the absence of the company’s sound effect, besides the change in the name of some stages (Spring Yard Zone is known as Sparkling Zone, for example) and boss presence only in Green Hill Zone.
Check out the gameplay in the video for just over an hour below:
