The neatest part of Sonic Generations is the homage it pays to past generations of the game. Bonus artwork and other locked rewards are also available to earn when finding certain items or spending earned points in the skill shop.

Finding and freeing Sonic's friends and restoring the times and places that are being threatened by the Time Eater and Doctor Eggman. Collecting 100 rings or finding a monitor in an item chest will get an extra life for sonic. Collecting golden rings gives a damage buffer against losing one of the five starting lives, red rings will give access to new abilities. Each sonic, classic and modern, is required to do a level in each area. This game is about going fast while platforming and finding rings and chaos emeralds, fans of the series won't be too befuddled by the game play and mechanics. The game is a nice homage to twenty years of Sonic the Hedgehog and was generally received with positive reviews, which was nice as the recent crop of Sonic games up to that point had floundered. Players get to play through classic Sonic levels, levels from the Dreamcast era as well as levels from modern systems. The enemy, a time eater, supplies the premise as it creates time holes, pulling Sonic through three different eras of Sonic the Hedgehog. Generations truly is a game that spans the generations of Sonic, and allows players to play as both classic and modern versions of the speedy blue hedgehog.

Sonic the Hedgehog has been around for 20 years, as of 2011, and to commemorate this monumental achievement, Team Sonic released Sonic Generations. Play as one of Sega's most iconic characters in this 20th anniversary game
