EDIT:Sanus, the storyline in Sonic Unleashed is bloated and silly just like both Sonic Adventure, Shadow and Sonic 06... Sonic games shouldn't be about time travel, giant monsters, the apocolypce, different dimentions or the planet breaking apart because of an evil giant god thing.
Sonic games should be about Sonic saving some little helpless creatures, like woodland animals or even these wisps from Robotnik loony plans... Which should also not be too serious and not make a whole lot of sense.
That is not quite true, it might be a 2D platformer but it is based around speed based action, whilst the original were based on momentum building, big difference in the two.
But what I was saying was that even for what ever shortcomings you may find it is still THE CLOSEST to the classics then anything in many years.
Also, I think that is very much down to opinion... While I havent played it, Nuckles has and he had some good things to say about the pacing of the levels. But what ever... This thread isnt about Sonic 4 and I can't be bothered to argue with you about it again.
