@Sharky on Sonic Adventure stuff. Sorry for the late reply. =/
You cannot agree to disagree because most of what I said is a fact and not an opinion. The classic Sonic stuff would not return at all if there was no demand for it, for example.

On the new trailer: I like it. Spagonia looks way, way, way better, but it is still kind of an annoying inclusion. One scene in particular near the middle has what seems to be six different paths to take even, very impressive!
Whatever the Sonic Heroes level was called also looks nice, but I really could not be less interested in playing it. I know it is going to be the "Water" level with this redesign, but we have just seen it a million times now. I have a similar annoyance with Green Hill Zone, but Generations would not have been complete without it, obviously.
I wish they would not use that licensed song though. It seriously sucks and will not even be in the game. What is the point?
