Common gameplay
The gameplay for primary games is mostly in line with previous installments as it allows the player to play with Sonic and sometimes other characters to explore several levels (called Zones) while collecting Rings and destroying Badniks with each zone usually counting with a boss whose difficulty level is usually higher than the obstacles faced earlier.

Trivia

 * The series mostly focus on the video game universe although characters and elements from other continuities (such as comics and animated shows) appear as well.
 * New characters are introduced.
 * Due to being a new continuity, the series' developers granted they'd avoid some of the mistakes done in later installments (like overusing the Deadly Six and Classic Sonic, downplaying some characters in favor of others like Shadow and wasting the potential of characters such as Silver and Blaze).
 * Unlike other games, Rings are no longer used as health as the series establishes a health bar to show how much you hurt, being possible to be filled by smashing Badniks and Item Boxes.
 * Across Mobius and Freedom Fighters are considered non-canon to each other, yet both follow elements in games.
