Editing Sonic the Hedgehog 4: Episode I (section)

===Criticism===
''Sonic the Hedgehog 4'' has been criticized due to the design and content of the game. Some people believe that it is not a true sequel to the classic games, due to ''Episode I''<nowiki>'</nowiki>s content being largely based on that of previous games with minor changes, and level design that features speed boosters in every level (a staple of [[Dimps]]' level design with their previous ''Sonic'' games) and object placement that forces the use of the [[Homing Attack]]. The latter is a move that some fans do not feel belongs in a 2D game, particularly not one based on the classics and set before its debut in ''[[Sonic Adventure]]''. The music has also been criticized, due to it featuring low-quality synths and drum samples (the latter from the first two ''Sonic the Hedgehog'' titles, not the more advanced ones from ''[[Sonic the Hedgehog 3]]'') that vary little between songs.

A highly controversial item is Sonic's design, which is the modern style model that debuted in ''[[Sonic Adventure]]'' and has since received refinements until its most recent state in ''[[Sonic Unleashed]]''. Many fans believe that the classic Sonic design should have been used and a petition was set up for Sega to include the different version.<ref>{{Cite web|title=Bring the Classic Sonic to Sonic the Hedgehog 4|url=http://www.gopetition.com/petitions/bring-the-classic-sonic-to-sonic-the-hedgehog-4.html|work=GoPetition|archiveurl=https://web.archive.org/web/20140804125835/http://www.gopetition.com/petitions/bring-the-classic-sonic-to-sonic-the-hedgehog-4.html|archivedate=4 August 2014}}</ref> However, in a magazine, [[Takashi Iizuka]] said that the classic style wasn't returning, as all games since ''Sonic Adventure'' have featured Sonic in his modern design (excluding ''Sonic Generations'' for having both Sonics in the game).
