One aspect of the Sonic the Hedgehog games that tends to go underappreciated is their level variety. From bright and flashy casinos to spooky haunted mansions, this series has introduced a plethora of unique stages for players to jump into and enjoy, but there's a select few entries in the franchise that really go above and beyond with the number of levels they provide. Considering Sonic games are designed for replayability, having as many stages as possible encourages players to lace up their running shoes once again to try and reach a high score on each one.
