Yet they were able to create all those miles of levels 17 years ago? I don't buy that for a second. They are saying it takes less time to create and design the entire gameplay model for the werehog complete with all of his animations, moves and miles of levels rather than a few more sonic stages?
Sonic unleashed has about 3 minutes of Sonic gameplay for every hour. No other sonic game is that bad, and Sonic Adventure is over 8 years old now. They should be able to make at least that level of game now.
