Sonic Generations (InstanceTopic, 20)
From Compile Worlds
Sonic Generations is the newest game in the Sonic series, available on PS3, Xbox 360, and Microsoft Windows via Steam. There is also a 3DS version available, although this features a completely different set of levels.
It (once again) features only Sonic himself as a playable character, though you can choose between "classic" and "modern" play styles. The game features a wide variety of rehashes levels from games all throughout Sonic's video game history, and plenty of epic music to match.
