Yes, jarring to those who liked it and expected.
Joyfully and relaxing to those who didn't like Sonic with "let's pretend we are making a RPG" story from Sonic Team, and we were happy to go back to the more standard classic Sonic of show the plot for a basic story. For someone like me, whose favourite Sonic video game story is still Sonic 3 and Knuckles (taking place over two days with Knuckles after Sonic's), it was great to go back to simple presentation to fit my Mega Drive nostalgia.
See, we can defend either having a story or not having a story, so let's stop using "indefensible".
Sonic Rush and Sonic Rush Adventure would have been so much better without all the talking in it. Sigh.
Oh and my Mega Drive, Master System, Game Gear Sonic, didn't talk, and that's how I remember him.
I was kidding at that last bit, though the idea is a bit funny in my mind.
I call lies. You dream of Morgan Freeman in a Sonic game constantly. I disagree with the idea of him as Sonic though. Freeman is more of a Motobug if anything.
