This video was edited by me in 2017, using previously unreleased footage of the Sonic Synergy game (as was Sonic Boom: Rise of Lyric once was called) and uploaded on Cisonic's RUclips channel.
The purpose of this trailer was to create awareness on this wonderful concept and the fact that the game looked much better on PC. Unfortunately, we all know that Sega forced the developers (Big Red Button) to port it to the Wii U because of contractual agreements with Nintendo.
Hopefully, one day, the archives will be opened by the wonderful people of Big Red Button and we can see Sonic Synergy released on PC as it was meant to be.
