I never said this was going to make the game unfun. My point was that out of all changes made to this entry in the series, that was the only major gameplay change that felt very un-Sonicy to me. Many 2D platformers for example, gave you a run button which gave players the option to go into two different speeds. One of the unique aspects of the Sonic series since the very first Sonic game was how Sonic progressively ran faster which helped make Sonic stand out against its competition. Since then, every console Sonic platformer to come out since the first game allowed gamers to run progressively faster just by moving the dpad or analog stick. Sonic Lost World changes that, but I don't view that as a bad thing. It's more difficult to have that mechanic work in a 3D environment so moving that functionality to a run button makes a lot of sense. However, instead of having the run allow you to progressively go faster, you immediately gotta go fast which makes a long lived mechanic in the franchise seem completely abandoned in this game. As for how fun I think this game looks, Sonic Lost World is shaping up to be a great game and I'm hoping it'll be even better than Sonic Generations. However, I have no intention of getting a Wii U so it might be a long time before I'm able to play it.
