Man, these are some of the most divided reviews I have ever seen. The reactions range from "it's time to end the franchise" to "this is the best sonic has ever worked in 3d". If anything I hope they keep the slower speed, a simple, colorful art style, and a greater focus on platforming in later entries.
Sterling, in a surprising twist of fate is one of the game's biggest supporters.
"Sonic Lost World can wildly swing from brilliant to horrific at the drop of a hat, but when one steps back and takes a look at the whole production, one sees far more to love than hate. Certainly, the nastier elements prevent it from being the truly great installment it could have been, but the experience is good enough to where I would desperately entreat Sonic Team to keep doing what's been started here. Please, no more desperate shifts in tone and level design, no more dramatic new overhauls. On a fundamental level, Lost World absolutely nails it, and does what Sonic should have been doing a long, long time ago. "
