Sonic X Shadow Generations primarily serves to introduce fans of the Sonic movies to everything that makes the games special. With Sonic Generations being designed as a sort of interactive history museum for the mainline games, Shadow Generations comes in as a playable overview of Shadow the Hedgehog as a character, which was released just prior to Sonic the Hedgehog 3's theatrical debut. That said, Sonic X Shadow Generations is one title that die-hard fans won't want to miss out on, as though it may act as an introductory title for many new players, it resurrects long-standing series lore to create a package full of references, nostalgia, and even closure for fans of Sonic Adventure 2 and Shadow the Hedgehog.
