The E3 trailer definitely looks like a different kind of Sonic game. It looks interesting as well. The combat sections look kind of like the Werehog's levels in Sonic Unleashed. I hope the controls are good and the gameplay is diverse and fun, so that those sections will be more fun than the Werehog's levels. The other sections look cool too, that energy beam could be a good gameplay aspect if it is done right and doesn't get too repetitive.
I'm looking forward a bit to this game; I may buy the Wii U version if it gets good reviews and if I like what I see and hear from it. I have to decide on it more though, but it doesn't look too bad right now. I hope the game is finished, well made and the controls will be good, otherwise that will make me mad and probably make me think again about buying it. Since it is a different Sonic game than the recent games and is a spin-off, people will be more critical of it. I definitely want to see the game be a success, be good, and for it to sell well.
