The issue Shenmue 3 so face is how far Yakuza series has come. It might not have quests as in depth as Shenmue, but combat and variety of quests will be compared.
Virtua Fighter never got the traction that Tekken did since it was slower and far more technical. It would be nice to see though start direction he takes it in.
A new outrun would be nice as long as it ain't open world.
It's a shame he isn't thinking about Space Harrier, considering the tech available now, he could make it like Rez Infinite where you can play on the TV or VR. Space Harrier was beyond its time.
