Tamaki, writer for Unseen64, has made a video that sheds light on what went wrong during the development of Sonic Boom: Rise of Lyric. And if you assumed that Big Red Button had to put up with a lot of crap that made it unreasonable to expect them to put out a good game, you’d be right.
The video explains various things that went wrong like how the studio had to switch from developing for next-gen hardware to the Wii U (which is why early footage looks better than the final game), bad working conditions and more. Be sure to give it a watch, especially if you thought that the game being so bad was just because of the developers being incompetent.
By the way, something I noticed while looking up the reveal trailer: SEGA made the video on their official Youtube page private. I wonder why…
