Tiffany Shafer states, "Although the entire game is fairly short, and there are only four boss battles, Sonic Generations offers a lot of content worth playing again. There are a load of unlockable challenges that become available after completing the game once-through. Plus, the mountain of multi-pathed choices in each level makes Sonic Generations worth replaying over and over. Sonic Generations is a must-play for old-school Sonic buffs. Yet, it is definitely fun enough to create new Sonic enthusiasts, as well."
