I haven't played Sonic Unleashed, so I don't know for sure, but I think that most Sonic fans hate it, and that's why Sega isn't going to make a sequel.
1:It depends on the system.(correct me if i am rong i wont get mad)2:it depends on the type of SONIC/UNLEASHED.
No Sonic Unleashed was a one time game that will not have a sequel.
Not proven so, but most likely no, as it was just a one timer with Sonic as a werehog, I do think it is canon but, there will not be a direct Sonic Unleashed sequel. Cross your fingers that once Sonic 4 is done they will make a Sonic game with similar styles to Unleashed.
sonic adventure 3? sonic unleashed 2? or sonic heroes 2?
No, Shadow is not in Sonic Unleashed.
Probably not.
No Sonic Unleashed was released instead
1, its called nazo unleashed and 2, no.
Sonic Unleashed was a one-timer, there won't be a second one.
