I adore the Sonic games for the Genesis and I really enjoyed the two Sonic Adventure games for the Dreamcast. Sonic was awesome because it required you to think real fast and react quickly while blazing through some really cool looking levels. Maybe other people enjoy, excuse me, enjoyed Sonic for different reasons, but that was it for me.
I hold judgment on this game though because if the Sonic Team can somehow maintain the speed of Sonic and add swordplay, that would be amazing. I find it highly doubtful though. Or, if they announce that this is a Sonic RPG I'd be okay with that. I think Sonic in an RPG is a bad idea but hey, I guess it can't hurt. But if this is like some other recent Sonic games, I think I may cry a little.
Maybe this game isn't real though; maybe someone has awesome photoshop skills. I found this photo on Kotaku though, so my guess is that it's real.
