Drop the sidecast, stop thinking about the fanbase, have Sonic as the speeding fast, somewhat cocky but uktimately kind hero that he is, Drop all humans except for Robotnic. Maybe they should re-hire sonic team and get them to play games like, I dunno, tomb-raider, mirrors edge, assasins creed and a couple of racing games while doing cocaine. What follows would would probably be some of the most fast-paced, flowing and fun level design in history. Frankly I think they could make some more good sonic games, but that's the crux of the whole argument. Stop thinking of it as making a revival of Sonic, because in games, the ageing process can either be that of a fine wine (Getting better as the years go on while still retaining the original qualities) it can also be like the ageing effect for a glass of milk (The longer you leave it to stagnate, the more mould and maggots are gonna be swarming it). We all know that the sonic games haven't aged well, but they should go at it with an approach of being almost completely unconnected to the dark-ages of the franchise, that way they won't be trying so hard to please the retard fanbase of Sonic, that way it'll have no ties to the equally retarded and especially confusing and delapidated settings, stories and characters of the other, shittier sonic games.
