Sega is keeping the Sonic Mania train rolling with Sonic Mania Plus later this summer and also a five-part series of animated shorts, the first episode of which is out now on YouTube.
"Sonic has just arrived back after the events of Sonic Mania and Sonic Forces, but something is already amiss. What are the huge holes being dug in the ground? And why is Eggman already capturing more animals? The story begins here, with the first of five parts in: Sonic Returns!"
Much like the game's intro, the animation is just wonderful to look at, but more than that, I like how they kept it light and fun. You're in, you're out, and you're left feeling good. There's no baggage!
