I seriously don't believe this game is rushed. It will be two years between Generations and this game, which is quite a lot of time for this team actually.
EDIT: Also if you have played the game, I have a few questions:
1. is it fast (I mean Unleashed fast)
2. are its problems of the same kind as Unleashed's "problems" minus the Werehog, as in very fast, difficult, no "momentum" gameplay? Because really, someone saying a Sonic game sucks can mean all kinds of things, Unleashed is my favourite 360 game and it rated worse than Sonic 2006 on some websites (a game that I despise).
1. for some stages you'll be blazing, in others you will not. Different stages can mean lots of different types of play styles...
2.Yes in the fast sections there is no "momentum" which is to say you just stop. And there are a lot of obstetrical that make you all the sudden stop in those sections.
If a mod is up in here you want to clean up my posts and delete them? I'd like to share more, but you have brought up a good point Yoshi. Is there an anonymous section to upload info like this?
