Honestly I would love ALL of the Sonic 1-3&Knuckles + CD zones in this game... Maybe as DLC.
A re-imagining of the 2D levels of Unleashed would be cool too, the Chinese, Savannah and Arabic levels were amazing.
Beware what you ask...
Yeah its real (Sonic Unleashed port to pre-smartphone mobiles developed by Gameloft). And yeah it sucks.
