Speedrunning Sonic games seems to uncover a great reversal: Sonic 06 is infamously terrible, but apparently makes a great game for speedrunning, because all its glitches are consistent and useful. Meanwhile, Sonic Colors is a very good game overall, but a speedrun doesn't look all that different from a standard run, so those who run it don't have all that much to say about it while playing.
There's an MST3K-like element here: the worse and more broken the game is, the more entertaining it is.
