I haven't actually played Sonic '06 yet, but I do count two major flaws in their criticism:
First, the very first point, where they claim giving Elise(sp?) the blue emerald means the entire series could not have happened. HOW SO? If Silver is from the future and he brought the blue emerald into the past, then essentially there are two blue emeralds, and obviously the other blue emerald is the one Sonic has been using all those other games.
Second... So Sonic '06 is bad from the storyline standpoint...
Especially considering that this is a series where for the first twelve or so games all Robotnik ever did was try to capture the Chaos Emeralds for whatever reason, except for that one time he decided to kidnap a bunch of magic birds, or steal sonic's shoes, or build a big fortress modelled after a pinball machine, and where Tails was twice able to catch up with a high-tech battle fortress using an old-fashioned biplane.
I'm not even going to mention that we're talking about the quality of the story in a series about a blue hedgehog who fights a mad scientist, whose inventions are constantly destroyed by said hedgehog jumping into them.
Story, I think, is given more credence in today's games than it really deserves. It doesn't really help that the video game industry has a totally effed-up notion of what a "good story" is anyway, but that's a rant for another time.
