Holy cow, Sega is finally giving the fans what they want! First, they revive the Shenmue brand and now Streets of Rage! If someone would have told me three and a half years ago that Shenmue 3 and Streets of Rage 4 would both be announced, I would have declared them insane!
Concerning the trailer itself, most of the NPCs and also Blaze look fine but Axel with a hipster beard? If they intend to leave him the way he looks now, this is gonna take a lot of time getting used to. In general I'm not really big on this "Comix Zone" art style but I can put up with it.
The music needs a lot less guitars and more of the old electronic sound though. Doesn't evoke any SoR feeling at all at the moment. But if they really can get Yuzo Koshiro, then nothing can go wrong, with the Grand Master of video game music on board.
All in all I'm very much looking forward to this. It will probably be a day one purchase for me and it will be a very happy day, seeing this venerable old Sega brand revived.
